The manufacturer‘s address is given on the last page of these operating instructions. 07 2 Safety instructions 2.1 Intended use Switching devices of the KL, KLF and T series are factory-assembled, type-tested switching devices. Please refer to the nameplates for all ratings. Each switching device is subject to a routine test at the manufacturer‘s where its equipment is checked against the order at the same time, and thus they are checked for proper fitting and operational liability. The switching devices are appropriate for the use in indoor switchgear. The switching devices may only be operated, repaired and maintained by authorised personnel who are instructed and trained appropriately. These operating instructions must be read carefully before the installation and commissioning of the switching devices. All provisions and instructions referred to in these operating instructions shall be observed properly during the installation, commissioning and operation. Each person authorised with the installation, commissioning, operation, maintenance and troubleshooting must have read and understood the operating instructions and in particular the chapter „Safety instructions“ as well as any other safety information. We recommend the user/operator to get a written confirmation of this. Operating errors may only be avoided and a trouble free operation ensured when the personnel involved knows the operating instructions. The general safety regulations and accident prevention regulations as required by law and possible rules of the insurance company, which can differ from country to country, must be necessarily observed during the operation and maintenance of the switching devices. These operating instructions are an integral part of the switching devices. The operating instructions must be handed over when the switching devices are relocated or sold etc. 2.2 Description of symbols and instructions Follow these instructions and be particularly careful and cautious in these circumstances. Pass on all safety instructions to all persons entrusted with working on the switching devices. In addition to the safety instructions laid down in these operating instructions, observe all general safety regulations and accident prevention regulations (VDE 0105 Part 100, BGVA3) at all times. Safety Symbol This symbol appears in this brochure next to all instructions relating to safety at work wherever a potential danger to life and limb exists. Warning against dangerous electrical voltage This particular warning sign warns against dangerous electrical voltage. Attention! Warning note This symbol appears in this brochure next to a paragraph that must be paid particular attention to so that rules, regulations, instructions and the correct operational procedure will be observed and damage to and destruction of the switching devices be prevented. 08 2.3 General occupational safety instructions The switching devices are designed and manufactured in accordance with the state-of-the-art and in consideration all safety instructions at all times. The switching devices may still constitute a danger to people and material assets if they are not used appropriately by personnel who have not been trained or specially instructed or if they are not used for the intended use or have been tampered with or if the safety instructions are not observed. Therefore these operating instructions must be read carefully and understood by all persons charged with the installation, commissioning, operation or maintenance of the switching devices. During the operation of these electrical switching devices certain parts are inevitably under a dangerous voltage and there may be mechanical parts – even remote-controlled – that move quickly. A disregard of these warning instructions may cause serious injury to people or damage to property. 2.3.1 Operation 2.3.2 Safety devices Responsibilities regarding the operation of the switching devices must be clearly defined and observed so that there are no misunderstandings regarding safety. Before commissioning and after maintenance work and modifications, the switching devices must be checked for their accident-proof and operationally safe condition by trained personnel. Before commissioning, persons staying within the hazard area of the switching devices must be warned and ordered to leave this area and remove all loose objects. The accessibility of the control elements must be ensured. The user must ensure that the switching devices are only operated when they are in proper working condition. Safety devices must not be modified, dismantled or taken out of operation. Unguarded parts of the devices may cause injury dangerous to life. Any modification affecting the safety must be reported immediately to the nearest responsible person. Modifications of the switching devices must not be carried out without the approval of the manufacturer and under the supervision of specialists. Specialists are persons who have acquired sufficient knowledge in the field of electrical engineering based on their specialist training and experience and are familiar with the relevant accident prevention regulations (BGVA3), instructions and generally recognised rules of technology (e.g. VDE regulations, DIN standards). All safety devices such as coverings must function properly and be fixed appropriately at all times. Switching devices must not be operated with faulty safety equipment. 2.3.3 Operational- and maintenance devices The tools and devices required for the operation, repair and maintenance of switching devices must be in an accident-proof condition and used without causing accidents. Any inappropriate and dangerous use of tools and devices with respect to the switching devices is not permitted. 2.3.4 Legal accident prevention regulations In addition to these accident prevention instructions and the safety instructions fixed at the switching devices the locally valid accident prevention regulations must be observed. 09 3 Application 3.1 Switch-disconnectors 3.2 Isolating switches 3.3 Type designation Switch-disconnectors are switches that are used for switching operating currents on and off and provide a visible isolating distance when switching off. Isolating switches are switching devices that may only be switched in de-energised state, i.e. without operating current. They provide a visible isolating distance in the switchgear. Because they are only switched in de-energised state no arc quenching devices (tilting tubes) are provided. The type designation specifies the details of the design. (Overview see item 7.5 on page 20) The tilting tube switch-disconnector is classified as a hard gas switch. These switches use a gas for arc quenching which will be emitted from appropriate plastics when an arc occurs. Type KL is appropriate for the use as cable switch, busbar transfer switch etc. Type KFL with an attached fuse base is intended for the use as a transformer switch. 10 4 Construction and method of operation 4.1 Base frame 4.3 Driving system The base frame is screwed together using bevelled steel section parts. They screwed on cast resin post insulators feature high resistance towards the influence of arcs, high cantilever strength and high creeping resistance. The switching shaft of the isolating switch T has free shaft ends on both sides which enable both right-hand and left-hand drive alternatively. 4.2 Conducting path The conducting path consists of a double blade made of silver-coated copper section. Each of the three conducting paths is supported by a free bearing at the respective bottom post insulator and engages into the fixed contact piece at the top post insulator. The conducting paths are actuated from the switching shaft by means of fibreglass reinforced plastic rods (coupling rods). The tilting tubes of the switch-disconnector, which are positioned between the contact blades, are used for interrupting the current and quenching the arc. In the normal design of the switch-disconnector KL a spring drive mechanism is installed on the right-hand shaft end. This spring drive mechanism causes a quick-ON and quick-OFF switching of the device. The switch-disconnector KLF is equipped with a stored-energy mechanism on the right-hand shaft end. The stored-energy mechanism consists of the quick-ON device, the tripping device for initiating the switching-off of the switch-disconnector by a shunt release or the striker pins of HV fuses and the storage spring for quick OFF switching. The switch-disconnector KLF can be switched off optionally both via the shunt release and the drive mechanism (switching lever, linkage mechanism, motor drive etc.) for which the driving element is used to turn the perforated disc into the direction of switching-off. After ca. 20 degrees the switch disconnector will be switched off . The complete switching off is finished after about 90 degrees of turn. For switching the switch-disconnector KLF on after it has tripped, the spring mechanism must be tensioned for which the driving element is used to turn the perforated disc until the stop in the switching-off direction is reached. Then the switch-disconnector is switched on by turning the perforated disc into the switching-on direction until the stop is reached. The mechanism acts indirectly and quickly upon the movable contact blades so that their speed is largely independent of the actuation of the mechanism. All switch-disconnectors can also be delivered with left-hand drive (optional equipment). Figure 4.1 Tilting tube 11 136 4.4 Arc quenching device – tilting tube 3 1 Now the current flows within the tilting tube via the switching pin and contact pieces whilst the tilting tube is pulled apart like a telescope. The switching spring is tensioned until it overcomes a catch, separates the switching pin from the contact pieces and pulls it into the quenching tube. The breaking arc burns within the tilting tube in a narrow annular gap between the quenching tube and the tip of the switching pin (Figure 4.3/3). 50 87 2 The break motion first separates the contact blade (double blade) from the fixed contact piece (Figure 4.3/1 and 2). However, the upper end of the tilting tube remains temporarily supported by its spherical head in the retaining spring. 114148033 Both parts are made of a gas-emitting plastic. As a result of the heat generated by the arc, sufficient quenching agent is released to quench the arc rapidly and effectively. Figure 4.2 Tilting tube 1 4 2 5 The hot gases escape downwards through the cooling grid of the tilting tube. They are cooled so much that they leave the tilting tube without flame effect. Only at this stage the spherical head of the tilting tube is released from the retaining spring (Figure 4.3/4) as a result of the continuing brake motion of the double blade. The return spring brings all parts of the tilting tube back to their initial positions whilst a twist spring at the retaining clip swivels the tilting tube back to its resting position within the double blade (Figure 4.3/5). Ignition processes only occur when the device is switched on between the main contacts of the switch-disconnector (Figure 4.3/6) so that high short-circuit currents cannot damage the arc quenching device. A replacement of the quenching device is only necessary after a great many of switching operations. 3 6 114148032 Figure 4.3 12 5 Transport, installation and commissioning 5.1 Transport p The switch-disconnectors are delivered in cardboard boxes. It must be ensured that the cast resin post insulators and conducting paths as well as the connection contact pieces do not collide and are not subject to excessive mechanical stresses. m m > Perforated disc la nu An a rg 2 /= 5.2 Installation Any works at the switching device must be carried out by skilled personnel and the operating instructions, accident prevention regulations and regulations of the employers‘ liability insurance association must be observed. As a basic principle the installation must be carried out with the power switched off. The regulations and generally recognised rules of technology (VDE regulations, DIN standards, IEC standards) for working in medium-voltage switchgear must be observed. Attention! Do not actuate the switch-disconnector before its installation! 1. The switch-disconnector shall be switched on when being installed. It will be fastened in the framework by four M12 screws (plus 2 screws for fixing the fuse). Long holes allow a slight shifting of the device in horizontal and vertical direction. Avoid deformation of the base frame. 2. Tilting tube switch-disconnectors in standard design are suitable for vertical wall mounting. Additional parts are attached when the switch-disconnector is to be fastened to the ceiling (hanging) or to the ground (lying) in order to adjust the switching speed accordingly. Please refer to the base frame for information about the permissible mounting position. 3. The connection bars must be adapted in such a way that virtually no tension, compression or torque is applied upon the upper or lower connection contact pieces when tightening the connection screws. Switching shaft Driving lever Figure 5 114148034 4. If a driving lever is flanged to the perforated disc of the switch-disconnector, it must be ensured that the annular gap between the disc and the switching shaft (30 mm diameter) is never smaller than 2 mm (Figure 5). 5. The M12 connection screw for the earth conductor is positioned in the frame part (Figure 0.1 and Figure 0.2). 6. After the installation of the type KLF tilting tube switch-disconnector, the contact blades are to be pulled by hand into the OFF position, then the tripping springs are to be hung into the welded-on hooks at the switching shaft using the tied handle (see Figure 0.2, Position 14) 7. The provided fuse separation plates at the devices, having a pole centre spacing of 135, 175 and 230 mm, must be mounted at the average conducting path. (see Figure 0.2, Position 16) Attention! The paraffin lubricant must not be removed from the contacts. Grease must not be used for lubricating the contacts. 5.3 Commissioning The commissioning must be carried out by skilled personnel only who must observe the operating instructions, accident prevention regulations and regulations of the employers‘ liability insurance association. After the switch disconnector has been installed by a competent person, clean the post insulators and coupling rods using a dry cloth before the commissioning. Check whether auxiliary lines coming from outside for auxiliary switches and shunt releases, if applicable, have been connected properly (circuit diagram). Check the connections of auxiliary lines and busbars for tight fit. Check the functionality of the switch-disconnector by repeated switching without voltage. All tilting tubes must be exactly latched in the retaining springs after switching on. 13 6 Maintenance Any works at the switching device must be carried out by skilled personnel and the operating instructions, accident prevention regulations and regulations of the employers‘ liability insurance association must be observed. Basically, any maintenance work must be carried out on de-energised equipment. The regulations and generally recognised rules of technology (VDE regulations, DIN standards, IEC standards) for working in medium-voltage switchgear must be observed. The switch-disconnectors require very little maintenance owing to their simple construction and the rugged design of the components. Inspection and maintenance work will become necessary: – after an operating time of about 4-5 years depending on their application conditions and the respective climatic and atmospheric ambient conditions. – after 1000 switching cycles with negligible currents. – after major disconnection loads We recommend to carry out the following procedure for the necessary works: Note! Paraffin, that is appropriate for lubrication, can be bought from the manufacturer‘s customer service. 1. Switch the device off; for type KLF trigger the stored-energy mechanism so that the energy storage mechanism is released. 2. Attention! 3. 6. 7. Clean the switching device with a dry and lint-free cloth. Major contaminations can be removed using a safety cleaner like Rivolta A.C.S. cleaning spray1) or Rivolta M.T.X. 60 forte Intensive cleaner1). Check the insulating parts (Figure 0.1/2, 6 and Figure 0.2/2, 6, 17) for mechanical damages and possible formation of creepage distances. 4. Check wear of contact surfaces at connection contact pieces (Figure 0.1/3 and Figure 0.2/3) and at the inner surface of the contact blade ends. In case of excessive wear of the silver layers (copper is visible) these parts must be replaced (to be done by manufacturer‘s customer service). 5. Apply paraffin by rubbing it on the connection contact pieces (Figure 0.1/3 and Figure 0.2/3) and at the inner surface of the contact blade ends. In the case that grease was applied as a contact lubricant by mistake, clean the connection contact pieces and the ends of the contact blades first using a grease solvent, e.g. Rivolta A.C.S. Cleaning Spray1) or Rivolta M.T.X. 60 forte Intensive Cleaner1) . Attention! Paraffin must not get into contact with grease! Attention! It must be ensured that the melting point of the paraffin used is not below 70°C. Lubricant is not allowed at the retaining spring (Figure 0.1/4 and Figure 0.2/4) and the spherical head of the tilting tube. Lubricate all moving drive parts with grease, Rivolta S.K.D. 40021). Lubricate the switching shaft bearing with lubricating oil, Rivolta S.K.D. 161). Note! For the inspection and maintenance of the arc quenching device – the tilting tube – contact the manufacturer‘s customer service. 8. 9. Check all screwed connections for their tight fit. Switch on the switching device a few times before a restart and check for proper functioning. 1) Rivolta products by Bremer + Leguil GmbH in Duisburg. For loosening tight parts use Rivolta T.R.S.Plus penetrating oil from the same manufacturer. 14 7 Technical data 7.1 Tilting tube switch-disconnector KL Switching devices up to 24 kV for indoor conditions Switch-disconnector without fuse base Standards KL20/630-275 KL20/630-230 KL15/630-210 KL15/630-175 KL10/630-210 KL10/630-135 Type IEC 60265-1 ; IEC 62271-1 Classification Multi-purpose switch disconnector, class E1, M1 Rated voltage Ur kV Rated frequency fr Hz 50 50 50 50 Rated lightning impulse withstand voltage to earth and between phases/across isolating distance Up (Uw) kV 75/85 75/85 95/110 95/110 125/145 125/145 Rated short-time withstand alternating voltage to earth and between phases/across isolating distance Ud kV 28/32 28/32 38/45 38/45 50/60 50/60 Rated current Ir A 630 630 630 630 630 630 Rated peak current Ip kA 50 50 50 50 40 40 Rated short-time current Ik kA 20 20 20 20 16 16 Rated duration of short-circuit tk s 1 1 1 1 1 1 Rated short-circuit making current Ima kA 50 50 50 50 40 40 Number of operations with rated short-circuit making current (E1) n 2 2 2 2 2 2 Rated system breaking current (for 10 cycles) I1 A 630 630 630 630 630 630 Rated ring-main breaking current (for 10 cycles) I2a A 630 630 630 630 630 630 Rated cable breaking current (for 10 cycles) I4a A 10 10 10 10 16 16 Rated overhead line breaking current (for 10 cycles) I4b A 1 1 1 1 1,5 1,5 Rated earth-fault breaking current (for 10 cycles) I6a A 30 30 30 30 48 48 Rated cable- and overhead line breaking current under earth fault conditions (for 10 cycles) I6b A 17 17 17 17 28 28 Mechanical operating cycles (M1) n Ambient temperature/indoor conditions T Altitude above sea level max.

Switching-on (when switched off) •Switching lever SH 50 upwards: The switch is switched on using the disc actuator and the linkage. •Switching lever SH 50 downwards: The switch is switched off by the disc actuator and the linkage. Note! The entire scope of delivery must be checked for completeness and possible transport damage immediately after its arrival. •Switching lever SH 50 downwards: The spring store for the trip-free mechanism of the switch is tensioned using the disc actuator and the linkage. •Switching lever SH 50 upwards: The switch is switched on by the disc actuator and the linkage. Operation Switching-off The disc actuator EMS is operated using switching lever SH 50 (Figure 9.5/6). The switching lever SH 50 is inserted into the bore hole of the part of the disc actuator protruding from the switching point. •Switching lever SH 50 downwards: The switch is switched off by the disc actuator and the linkage. Attention! If disc actuators with optional interlocking are used, disengage the interlocking by pushing the switching lever in and switch the switch on. 44 Figure 9.4 1 Disc actuator 6.1 Linkage GK 11 Washer 2 Perforated plate 6.2 Linkage GT 12 Mounting of EMS actuator 3 Screw M8x40 (2x) 7 Bolt in the panel using 2 M8 screws, 4 Nut (2x) 8 Nut washers and spring washers 5 Spring washer (2x) 9 Spring washer (not included in scope of delivery) 6 Linkage 10 Splint (*) Cutout for EMS actuator in the panel 45 Installation and adjustment of disc actuator EMS with linkage GK at switchdisconnector KLF Attention! Do not actuate the switch-disconnector before it has been installed! Installation: 1. Provide cutout for disc actuator in panel (Figure 9.4/(*)). Install switch and disc actuator (Figure 9.5/1) in switchgear panel. Note! The switch-disconnector KLF is delivered in the switching position „RELEASED“, with detached tripping springs and contact blades in „ON“ position. Note! There can be other angles or fixing points than shown in Figure 9.5 depending on the structure of the switchgear panel. Attention! However, an angle of minimum 15° between the middle axis of the disc actuator (Figure 9.5/1) and the middle axis of the perforated disc (Figure 9.5/4) of the switch-disconnector must be observed. Figure 9.5 2. Pull the contact blades of the switchdisconnector KLF by hand into „OFF“ position and hang the tripping springs in. Attention! Do not touch the contacts of the switch-disconnector with greasy hands. 3. Fix the disc actuator on the side of the panel using two M8 screws, washers and spring washers. 4. Fix the perforated plate (Figure 9.5/2) at the disc actuator (Figure 9.5/1) using two M8x40 screws (Figure 9.4/3), nuts (Figure 9.4/4) and spring washers (Figure 9.4/5) perpendicular to below. (Disc actuator must be in „ON“ position). 5. Screw the perforated disc lever (Figure 9.5/3) to the perforated disc of the switch-disconnector (Figure 9.5/4) in an angle of approx 45°. 6. Shorten the linkage (Figure 9.5/5) to the required length (disc actuator must be in „ON“ position). Attention! Observe minimum overlapping (Figure 9.5/dimension X2.1). Restore the clamping connection according to section A-A (Figure 9.5). 7. Screw spherical-head side of linkage (Figure 9.5/5) to the middle hole of the perforated disc lever (Figure 9.5/3). 46 8. Screw the linkage at a hole (middle row of holes, if possible) of the perforated plate (Figure 9.5/2) in the end position „ON“ of the disc actuator. Attention! If the disc actuator is already in the final position without the perforated disc touched and you try to switch the switch-disconnector on there is the danger of a return stroke caused by the non-latched switching-on spring. In this case the linkage must be shortened by shifting it within the connecting plate. If this is impossible, the bolt-on point on the perforated plate (Figure 9.5/2) must be changed. The adjustments of the switch-disconnector drive are factory made and provided with sealing wax. The fine adjustment of the disc actuator should be carried out using the spherical head of the linkage GK/GT. 9. Tighten all screws before adjustment and functional test (torques acc. to screw qualities). Adjustment and functional test: Attention! In the final position „ON“ of the disc actuator the distance between the actuator bolt (Figure 9.6/1) and the perforated disc (Figure 9.6/2) must be approx. 15 mm. 12. When the switch-disconnector is switched on slowly, the release bolt (Figure 9.6/3) and the roll-latch (Figure 9.6/4) must not touch. Installation and adjustment of disc actuators EMS with linkage GK at switch-disconnector KL Installation: 1. Provide cutout for disc actuator in panel (Figure 9.4/(*)). Install switch and disc actuator (Figure 9.5/1) in switchgear panel. Note! There can be other angles or fixing points than shown in Figure 9.5 depending on the structure of the switchgear panel. Attention! However, an angle of minimum 15° between the middle axis of the disc actuator (Figure 9.5/1) and the middle axis of the perforated disc (Figure 9.5/4) of the switch-disconnector must be observed. Attention! Do not actuate the switch-disconnector before its installation! Attention! A distance of 3 mm must exist (Figure 9.8) to prevent an inevitable release. Note! The switch-disconnector KL is delivered in switching position „ON“. Figure 9.6 10. Switch the switch-disconnector off using the disc actuator and tension the switching-on springs. 2. Fix the disc actuator at the side of the panel using two M8 screws, washers and spring washers. 11. In the final position „OFF“ of the disc actuator the perforated disc (Figure 9.7/1) must be touch at the eccentric stop (Figure 9.7/2). 3. Fix the perforated plate (Figure 9.5/2) at the disc actuator (Figure 9.5/1) using two M8x40 screws (Figure 9.4/3), nuts (Figure 9.4/4) and spring washers (Figure 9.4/5) perpendicular to below (disc actuator must be in „ON“ position). Figure 9.8 13. After the adjustment and functional test have been completed, check all screws for their tight fit. 4. Screw the perforated disc lever (Figure 9.5/3) to the perforated disc of the switch-disconnector (Figure 9.5/4) in an angle of approx. 45°. 5. Shorten the linkage (Figure 9.5/5) to the required length (disc actuator and switch-disconnector must be in „ON“ position). Attention! Figure 9.7 Observe minimum overlapping (Figure 9.5/dimension X2.1). Restore the clamping connection according to section A-A (Figure 9.5). 47 6. Screw the spherical-head side of the linkage (Figure 9.5/5) to the middle hole of the perforated disc lever (Figure 9.5/3). 7. Screw the linkage at a hole (middle row of holes, if possible) of the perforated plate (Figure 9.5/2) in the end position „ON“ of the disc actuator. 8. Tighten all screws before adjustment and functional test (torques acc. to screw qualities). Adjustment and functional test: Attention! In the final position „ON“ of the disc actuator the distance between the actuator bolt (Figure 9.9/1) and the perforated disc (Figure 9.9/2) must be approx. 15 mm. 9. Switch the switch-disconnector off using the disc actuator. With optimum adjustment there should be a distance of approx. 15 mm again between the actuator bolt (Figure 9.9/1) and the perforated disc (Figure 9.9/2) in the final position „OFF“ of the disc actuator. When disc actuators with optional interlocking are used, the interlocking must be latched. 10. Should the same dimensions as described above not be achieved, readjust the linkage or use another hole in the perforated plate (Figure 9.5/2). Attention! If the distance is too small, the actuator bolt may hit in the perforated disc when switching which can cause a malfunction of the actuator and shall be strictly avoided. • Distance between the actuator bolt and perforated disc in „OFF“ position is too small: Extend the linkage (Figure 9.5/5) by shifting it in the connection plate (pay attention to Figure 9.5/dimension X2.1!). If this method is not sufficient, you can extend the path of the perforated disc by shifting the screw point on the perforated plate (Figure 9.5/2) into the lower row of holes. Bild 9.9 • Distance between the actuator bolt and perforated disc in „OFF“ position is too large: Shorten the linkage (Figure 9.5/5) by shifting it in the connection plate. 11. After the adjustment and functional test have been completed, check all screws for their tight fit. Installation and adjustment of disc actuators EMS with linkage GT at isolating switch T and earthing switches DES, EUK, EOK without spring-jump drive The linkage GT (Figure 9.4/6.2) differs from linkage GK (Figure 9.4/6.1) by the method of fixing it to the switching shaft. The linkage GT is used for switching isolating switches T and earthing switches DES, EUK, EOK without spring-jump drive. The claw (Figure 9.10/1) of the linkage is pushed over the switching shaft (Figure 9.10/2) and fastened by two clamping pieces. Figure 9.10 Fix the disc actuator and shorten the linkage in the same way as with linkage GK. 48 9.3 Rotary actuator, type DA This rotary actuator enables the immediate actuation of the switch fixed to a side wall of the panel. For this the actuating shaft of the switch is extended up to the outside wall of the switchgear on the side.

HV-fuse link selection HV back-up fuses, selection and application Notes The HV back-up fuses that are used for the short-circuit protection of transformers must be selected according to the present reference lists for switch-disconnector-fuse combinations, type KLF. Three HV back-up fuse links of the same type and of the same rated current of a listed manufacturer must be used in the switchdisconnector-fuse combination. If one HV-fuse link has released because of a grid failure, basically all three HV-fuse links in the switch-disconnector-fuse combination must be renewed. Even if the striker pin of a HV-fuse link has not tripped following a fault-current disconnection and it still has got some „continuity“, all three HV-fuse links must be thrown away into the recycling box. There is a great probability that the fuse elements are defect and do not feature any more current carrying capacity. If such damaged HV-fuse links being used any longer, the next malfunction with worse implications will be pre-programmed. When inserting the HV-fuse links into the HV-fuse holder it must be ensured that the striker pin side of the HV-fuse links points into the direction of the tripping lever of the switch-disconnector. HV-fuse links are sensitive towards mechanical shock loading. The fuse elements of a HV-fuse link can be damaged during heavy mechanical shock loading. We recommend to handle the HV-fuse links with care and not to remove the original packaging before they will be used, if possible. 50 10.1 6 kV operating voltage Switch-disconnector-fuse combination according to IEC 62271-105 Reference list for selecting the HV back-up fuses Switch-disconnector KLF 10/630-…-SU(SO) with fuse trip-free release 6 kV operating voltage Transformer HV-fuse links dimension „e“ 292 mm Rated power [kVA] Rated current [A] uK IK [%] [A] 100 9,6 4 241 125 160 200 250 315 400 500 630 630 800 12,0 15,4 19,2 24,1 30,3 38,5 48,1 60,6 60,6 77,0 4 4 4 4 4 4 4 4 6 6 301 385 481 601 758 962 1203 1516 1010 1283 Producer Rated voltage [kV] Type or Item Rated current [A] SIBA 6/12 3000413.20 / 3000413.25 20 / 25 Jean Müller 12 IKUS 10-32/12N 32 EFEN 6/12 67520.0200 / 67520.0250 20 / 25 SIBA 6/12 3000413.25 / 3000413.31,5 25 / 31,5 Jean Müller 12 IKUS 10-40/12N 40 EFEN 6/12 67520.0250 / 67520.0320 25 / 31,5 SIBA 6/12 3000413.31,5 / 3000413.40 31,5 / 40 Jean Müller 12 IKUS 10-50/12N 50 EFEN 6/12 67520.0320 31,5 SIBA 6/12 3000413.40 / 3000413.50 40 / 50 Jean Müller 12 IKUS 10-50/12N 50 EFEN 6/12 67520.0400 40 SIBA 6/12 3000413.50 50 Jean Müller 12 IKUS 10-63/12N 63 EFEN 6/12 67520.0400 / 67520.0500 40* / 50 SIBA 6/12 3001213.63 63 Jean Müller 12 IKUS 10-80/12N 80 EFEN 6/12 67520.0500 / 67520.0630 50* / 63 SIBA 6/12 3001213.80 80 Jean Müller 12 IKUS 10-80/12N 80* EFEN 6/12 67520.0630 / 67520.0800 63* / 80 SIBA 6/12 3001213.80 / 30001213.100 80* / 100 Jean Müller 12 - - EFEN 6/12 67520.0800 / 67520.1000 80* / 100 SIBA 6/12 3001213.100 / 3002043.125 (SSK) 100* / 125 Jean Müller 12 - - EFEN 6/12 67520.1000 100* SIBA 6/12 3001213.100 / 3002043.125(SSK) 100* / 125 Jean Müller 12 - - EFEN 6/12 67520.1000 100* SIBA 6/12 3002043.125 (SSK) 125* Jean Müller 12 - - EFEN 6/12 67520.1000 100* * When using a low voltage fuse link NH-class gTr consists of operations for the selection of a HV-fuse link with rated current that no selectivity.
