Siemens · 04/2018 9 © Siemens AG 2018 3WL1 Air Circuit Breakers 3WL1 Air Circuit Breakers/Non-Automatic Air Circuit Breakers up to 6300 A (AC), IEC General data Withdrawable short-circuit, grounding, and bridging units Undervoltage releases Portable positively-driven grounding and short-circuit devices are used for the disconnected system sections to verify isolation from the supply at the workplace. The undervoltage release causes the circuit breaker to be opened if the operational voltage falls below a certain value or is not applied. The circuit breaker cannot be closed manually or by means of an electrical ON command if the undervoltage release is not connected to the operational voltage. The undervoltage release has no delay as standard. A delay can be set by the customer in the range between td < 80 ms and td < 200 ms. Withdrawable grounding units allow simple and comfortable grounding. They are simply inserted into the guide frames in place of the corresponding withdrawable circuit breakers. This ensures that these devices are always first connected with the grounding electrode and then with the components to be grounded. The grounding contacts are fitted to the side of the breaker enclosure and establish the connection when inserted into the guide frame. Short-time current of the grounding contact kA 15 (500 ms) Rated operational voltage V 1000 (690 for size I) DIN VDE 0683 Standards All withdrawable contacts are short-circuited and grounded on delivery. Electrically skilled persons can easily convert them to withdrawable bridging units by following the enclosed instructions. In addition, the withdrawable unit can be adapted to various rated currents of one size. Withdrawable short-circuit and grounding unit The withdrawable short-circuit and grounding unit consists of a breaker enclosure with blade contacts which are connected with the short-circuiting link. Depending on the version, the short-circuiting links are arranged at the top or bottom. The grounding and short-circuit connections are established when the device is inserted. It must be ensured that the side to be short-circuited and grounded is not live. For this reason it is recommended that the withdrawable unit is only cranked in when the door is closed. Withdrawable bridging unit In addition, an undervoltage release with a delay in the range from 0.2 to 3.2 s is available. Closing coil The closing coil is used to close the circuit breaker electrically by means of a local electrical "ON" command or by remote means. Motorized operating mechanism The operating mechanism is used to charge the spring energy store automatically. The operating mechanism is activated if the spring energy store has been discharged and the control voltage is available. It is switched off automatically after charging. This does not affect manual operation of the spring energy store. Indicators, signals and control elements Motor cutout switch Selector switch for switching off the motorized operating mechanism (automatic charging). Operating cycles counter The motorized operating mechanism can be supplied with a 5-digit operating cycles counter. The display is incremented by "1" as soon as the spring energy store is fully charged. Resetting of the manual tripped signal When the circuit breaker has tripped, this is indicated by the protruding red mechanical tripped indicator on the ETU. When the mechanical tripped indicator is activated, the tripping solenoid and tripped signal are reset. If this manual display is to be reset remotely, the reset button can be equipped with a reset solenoid. The withdrawable bridging unit consists of a breaker enclosure in which all disconnection components and the operating mechanism have been replaced with simple connections between the upper and lower contacts. This option allows the circuit breaker to be reset both manually and electrically. Auxiliary releases When the ETU is tripped, reclosing of the circuit breaker is prevented until the trip unit is either electrically or manually reset. If the "Automatic resetting of reclosing lockout" option is used, the pre-tensioned circuit breaker is ready to close immediately after tripping. Resetting the manual "tripped" indicator is not included in this option. Up to two auxiliary releases can be installed at the same time. The following are available for selection: 1 shunt release or 1 undervoltage release or 2 shunt releases or 1 shunt release + 1 undervoltage release Automatic resetting of reclosing lockout Tripped signaling switch One signaling contact is used for each auxiliary release to determine the positions of the auxiliary releases. If the circuit breaker has tripped due to an overload, shortcircuit, ground fault or extended protection function, the tripped signaling switch can indicate this. This signaling switch is available as an option. If the circuit breaker is used for communication, this option is supplied as standard. Shunt releases Ready-to-close signaling switch When the operational voltage is connected to the shunt release, the circuit breaker is opened immediately. The shunt release is available in the versions 5% OP for overexcitation and 100% OP for permanent excitation. This means that it is also possible to block the circuit breaker against being jogged into closing. The 3WL circuit breakers are equipped with an optical ready-toclose indicator as standard. In addition, the ready-to-close status can be transmitted by means of a signaling switch as an option. If the switch is used for communication, this signaling switch is supplied as standard. Signaling switches for auxiliary releases An energy storage device for shunt releases allows the circuit breaker to be opened even if the control voltage is no longer available. 10 Siemens · 04/2018 © Siemens AG 2018 3WL1 Air Circuit Breakers 3WL1 Air Circuit Breakers/Non-Automatic Air Circuit Breakers up to 6300 A (AC), IEC General data Circuit breakers 28 1 2 3 4 1 2 27 26 3 4 25 5 24 6 23 7 22 21 8 20 9 10 19 11 18 17 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 12 13 16 14 NSE0_00965b 15 23 24 25 26 27 28 Arc chute Carrying handle Labeling plates Motor cutout switch (option) or "Electrical ON" (option) Type plate for circuit breaker Spring charge indicator "Mechanical ON" button Rated current indication Positioning pictogram Operating cycles counter (option) Hand-operated lever Crank handle Withdrawable unit drive shaft Equipment plate Grounding connection Position indicator Table for ground-fault protection Safety lock for crank handle (option) Mechanical unlocking of crank handle (option) Electronic trip unit Rating plug "Mechanical OFF" button or "EMERGENCY-STOP" mushroom pushbutton (option) Ready-to-close indicator Contact position indicator "Tripped" indicator (reset button) "Secure OFF" locking device (option) Operator panel Male connector for auxiliary connections Guide frames 1 2 18 3 17 4 1 2 3 4 5 6 7 8 9 10 11 5 6 16 7 15 14 8 13 12 13 14 15 16 17 18 Arc chute cover (option) Blow-out openings Opening for crane hook Shutter (option) Locking device (shutter) (option) Type plate for guide frame Isolating contacts Ground terminal Ø14 mm Locking device for racking rail Locking device against movement when cabinet door is open (option) Door interlock for guide frame (option) Racking rail Factory-set rated current coding Sliding contact for breaker grounding (option) Equipment-dependent coding (option) Shutter actuator (option) Position indicator switch (option) Sliding contact module for auxiliary conductors (number depends on equipment) 12 9 11 10 NSE0_00966b Siemens · 04/2018 11 © Siemens AG 2018 3WL1 Air Circuit Breakers 3WL1 Air Circuit Breakers/Non-Automatic Air Circuit Breakers up to 6300 A (AC), IEC General data Locking devices Sealing devices Locking device in OFF position Sealing cap for "Electrical ON" button This function prevents closing of the circuit breaker and complies with the requirements for main control switches according to EN 60204 (VDE 0113) – supply disconnecting device.

It enables systems to be adapted to the different protection requirements of distribution systems, motors, transformers and generators. Tripped indicator/ Reset button LCD alphanumeric with 15° inclination and rotatable through 180° Communication capability The international standardized PROFIBUS DP or MODBUS can be used to transmit data such as current values, switching states, causes of tripping etc. to central computers. Data acquisition and energy management are possible in conjunction with the Plus metering function. An internal circuit breaker data bus allows switchboard panel communication between the circuit breaker and typical secondary devices in the circuit breaker section: • Control of analog displays • Facility to test the communication build-up with circuit breakers • Display of tripping state and tripping reasons • Input module for reading in further switchboard panel signals and for transmission of these signals to the PROFIBUS DP or MODBUS • Various output modules for displaying measured values Slide switch for selectable overload characteristic Rating plug Ground-fault protection module (retrofittable) Example of configuration for ETU45B This means that it is not only possible to monitor the device remotely, but also to transmit current values from the entire system and perform switching operations remotely. I2t and I4t characteristic curves for overload protection The best protection for the whole switchboard is achieved by setting the tripping characteristic curve to an optimum value. In order to achieve optimal discrimination for upstream fuses or medium-voltage protection systems, the inclination of the characteristic curve can be selected for the overload range. The overload protection L (long time protection) for the ETU45B and ETU76B Electronic Trip Units allows the curve to be switched between the I2t and I4t characteristics. The I4t characteristic improves discrimination for downstream circuit breakers and fuses. Electronic Trip Units ETU High emphasis has also been placed on modularity during the development of the Electronic Trip Units. These are some of the modules which can be easily retrofitted at any time: • Ground-fault protection module • Communication • Metering function • Display • Rating plug This allows quick adaptation to new local power supply conditions. In addition, innovative functions have been included in the ETUs. Rating plug The rating plug is an exchangeable module which allows the user to reduce the rated device current so as to adapt it optimally to the plant; e.g. if a new plant section is put into operation. The rating plug must be selected to correspond to the rated current of the plant. 16 Siemens · 04/2018 Metering function Plus Selectable parameters In the case of quick changes of power supply conditions, e.g. for switchover from transformer to generator operation or if a section of the supply is disconnected when the shift changes, 3WL circuit breakers allow the relevant protection parameters to be quickly adapted to the new conditions. The ETU76B contains two independent tripping characteristics (parameter sets). The switchover is completed within 200 ms and is performed with the help of an external signal. © Siemens AG 2018 3WL1 Air Circuit Breakers 3WL1 Air Circuit Breakers/Non-Automatic Air Circuit Breakers up to 6300 A (AC), IEC General data ETU15B Electronic Trip Unit Application: Option: safety lock prevents pressing of reset button after overcurrent release Mechanical RESET for reclosing lockout and mechanical tripped indicator Indicator: overcurrent release activated Indicator: fault in overcurrent release Indicator: overload alarm Rotary switch for setting value, overload release Simple building and system protection without time-selective coordination up to 4000 A.

This setting can be implemented for the Electronic Trip Unit version ETU76B with Menu/Comm. Selection criteria for 3WL circuit breakers Basic criteria for selecting circuit breakers are: • Max. short-circuit current at place of installation of circuit breaker Ik max . This value determines the short-circuit breaking capacity or short-circuit current carrying capacity of the circuit breaker. • It is compared with the value Icu, Ics, Icw of the circuit breaker and essentially determines the size of the circuit breaker. See Figure "Overview of 3WL circuit breakers/non-automatic air circuit breakers". • Rated current In that is to flow through the branch circuit. This value must not be higher than the maximum rated current for the circuit breaker. The rated current for the 3WL circuit breaker is set with the rating plug. See Figure "Overview of 3WL circuit breakers/ non-automatic air circuit breakers" under "Design". • Ambient temperature for the circuit breaker. This is usually the control cabinet's internal temperature. • Design of the circuit breaker • Minimum short-circuit current which flows through the switching device. The trip unit must still detect this value as a short-circuit and must respond by tripping. Protection functions of the circuit breaker. These are defined by selection of the corresponding Electronic Trip Unit; see table "Functions of the Electronic Trip Units" under "Functions". © Siemens AG 2018 3WL1 Air Circuit Breakers 3WL1 Air Circuit Breakers/Non-Automatic Air Circuit Breakers up to 6300 A (AC), IEC General data 3WL circuit breakers for DC applications This version of the 3WL non-automatic air circuit breaker is suitable for direct current applications. The external protective device DIGmat S100 provides adjustable overload and shortcircuit protection for the 3WL non-automatic air circuit breaker. This is based on the measuring chain of a shunt resistor and the DIGmat S100 tripping unit. Shunt resistors are available for 1000 A, 2000 A and 4000 A (special ranges on request). They are in accordance with DIN 43703 and have a class accuracy of 0.5. A measuring-circuit voltage of 60 mV DC is picked off for the rated current In. The measuring-circuit voltage is a linear image of the primary current. DIGmat S100 The DIGmat S100 trip unit monitors the image of the primary current thus supplied and compares it with the tripping characteristic curve set on the device. The parameter settings on the DIGmat S100 apply also for DC feedbacks. Reversing duty is thus possible. • Short-circuit protection: Setting range Ii = 1.25 × IR to max. 4 × In Tripping occurs in less than 50 ms if the set value is exceeded. In IR tR Ii The tripping characteristic curve is determined and described by the following variables: • Overload protection: Setting range IR = 0.4 ... 1.0 In The characteristic curve has a I2t characteristic. The tripping time tR is selectable between 2 and 10 s, with tR defined for 6 × IR. = = = = Rated current of the circuit breaker Current setting value of the adjustable overload release Assigned tripping time of the overload trip Instantaneous tripping current of the adjustable short-circuit release The components are available only from the company mat – Maschinen- und Anlagentechnik: mat – Maschinen- und Anlagentechnik Dr. Becker GmbH Rudolf-Diesel-Straße 22 22941 Bargteheide Tel.: +49 (4532) 20-2101 Fax: +49 (4532) 20-2121 Email: info@m-a-t.de Internet: www.m-a-t.de ■ Configuration • The bending radii of the Bowden cable must be > 500 mm • The total bending angle across the length of the Bowden cable must not exceed 640° • If the circuit breakers to be interlocked are arranged vertically, the interlock mechanisms must be aligned • Circuit breakers to be interlocked must be arranged so that Bowden cables can be optimally installed in compliance with the conditions mentioned in the above points • The installed Bowden cable must be fixed (with cable ties or the like) before the interlock is adjusted • Select the width of switchboard cubicle to allow enough freedom of movement for adjusting the interlock! • Openings and cutout sections in system elements must be designed in such a way that the direction of the Bowden cables is not changed and that the wires are not obstructed when they are routed Mutual mechanical circuit breaker interlocks The module for mutual mechanical interlocking can be used for two or three 3WL circuit breakers and can be adapted easily to the corresponding versions. The fixed-mounted and withdrawable circuit breaker versions are fully compatible and can therefore be used in a mixed configuration in an installation. This also applies to 3WN6 circuit breakers. The circuit breakers can be mounted adjacent to each other or one above the other, whereby the distance of the circuit breakers is determined solely by the length of the Bowden cable (lengths: 2 m/3 m/4.5 m). Interlock signals are looped through using the Bowden cables. Interlocking is only effective in the connected position in the case of withdrawable circuit breakers.

An integrated and modular communication architecture was designed for the 3WL circuit breaker to ensure that it can satisfy these requirements. The core component of this architecture is the CubicleBUS, which links together all of the intelligent components within the 3WL circuit breaker and enables the easy and safe connection of other additional external components to the circuit breaker. The CubicleBUS is already incorporated and connected in all complete circuit breakers with ETU45B and ETU76B trip units. The high modularity of the system allows retrofitting of communication functions (e.g. metering function) at any time. Similarly, a non-communication-capable 3WL circuit breaker can be upgraded (e.g. changeover from ETU25B to ETU45B with CubicleBUS) easily on site in the plant. All modules connected to the CubicleBUS can directly access the existing source data of the circuit breaker, which guarantees the quickest possible access to information and response to events. Furthermore, additional external modules (including digital inputs and outputs, analog outputs) can be connected to the CubicleBUS to provide cost-effective solutions for the automation of additional devices in the switchboard.

Digital output modules are available in versions with and without a rotary coding switch. On modules with a rotary coding switch it is possible to choose between two signaling blocks each with 6 defined assignments and to set an additional response delay. All the digital output modules are available as a version with relay outputs (CO contacts, up to 12 A). Up to two modules of this type can be connected to one 3WL circuit breaker. Analog output module Digital input module With the digital input module, up to 6 additional binary signals (24 V DC) in the circuit breaker environment can be connected to the system. It is thus possible for example to send messages concerning the state of a switch disconnector or a control cabinet door to the PROFIBUS DP/MODBUS. With the digital input module on the CubicleBUS it is also possible for the two different protection parameter sets held in the ETU76B Electronic Trip Unit trip unit to be switched over automatically in a few milliseconds. It is thus possible, for example, to automatically change the parameters of a tie-breaker should the transformer infeed fail. Digital output module with rotary coding switch One module each of this type can be used for holding the six items of digital information and for automatically switching over the parameters. Digital output module, configurable The configurable output module is available for higher-performance solutions. With this module, random events on the CubicleBUS can be switched directly to one of six available outputs or three of these outputs can be assigned with up to six events. In other words, up to six events can be placed on one physical output with "OR" operation. Either BDA Plus or powerconfig is used for configuring. A relay variant is also available here the same as for the output modules with rotary coding switch. Only one module of this type is possible per 3WL circuit breaker. Digital input module ZSI module (short-time discrimination control) The use of ZSI modules is recommended when Siemens circuit breakers are arranged in several staggered levels but full discrimination with the smallest possible delay is to be assured nevertheless. Digital output module, configurable Analog output module The analog output module can be used to output the following measured values to analog indicators in the control cabinet door: • IL1, IL2, IL3, IN or • UL12, UL23, UL31, UL1N or • PL1, PL2, PL3, Stot or • p.f.1, p.f.2, p.f.3, I % or • favg, ULLavg, Ptot, p.f. avg Four 4-20 mA/0-10 V interfaces are available for this. The measured values to be output are selected with a rotary coding switch. By using the analog output module it is possible to do without additional converters and their conventional installation/ wiring in the main conducting path. Up to two modules of this type can be connected to one 3WL circuit breaker. 26 Siemens · 04/2018 The circuit breakers are interconnected by these modules. In case of a short-circuit, each affected circuit breaker interrogates the circuit breakers directly downstream whether the shortcircuit has also occurred in the next, lower level. The short-circuit is exactly localized as a result, and only the next upstream circuit breaker in the energy flow direction is switched off.

Only a selection is shown in the following. The characteristic curves each show the largest and smallest setting range of 3WL circuit breakers with 1000 A rated current at 500 V rated voltage with various trip units. In order to obtain a complete tripping characteristic curve, the relevant parts of the characteristic curves have to be combined. The characteristic curves show the behavior of the Electronic Trip Unit when it is activated by a current that is already flowing before the tripping operation. If the overcurrent tripping occurs immediately after closing and the Electronic Trip Unit is therefore not yet activated, the opening time is extended, depending on the level of the overcurrent by up to 15 ms. To determine the break-times of the circuit breakers, approximately 15 ms must be added to the opening times shown for the arcing time. For tolerances, see legend below. The characteristic curves shown apply to ambient temperatures at the circuit breaker between –5 and +55 °C. The trip unit can be operated at ambient temperatures of –20 to +70 °C.
