Residual Current Circuit Breakers
Doepke RCCBs meet EN61008 / EN62423
To reduce the risk of death or serious injury from electrocution and or fire, RCCBs are provided in AC circuits as an
additional means of protection and must operate reliably when other means of protection have failed.
Specifying, Purchasing and installing low quality products could endanger people's lives and put property at risk.
Doepke RCCBs are manufactured in Doepke factories based in Germany, with individual testing and recording of the
trip characteristic and a unique serial number marked on each product. This ensures that every product leaves the
factory in safe working order and conforms to the requirements of the relevant standard or standards.
RCCB's General Principles for Use
Selection and installation: by “skilled/instructed” (electrical) persons only. Refer to the IET Wiring Regulations for
guidance on the selection and use of RCCBs to meet the requirements for new and existing installations.
The references below are based on BS 7671: 2008 incorporating Amendment No 3: 2015.
Protection in the event of indirect contact - Fault Protection.
Doepke RCCBs manufactured to the above standard are designed to protect persons against the hazards associated
with indirect contact where exposed conductive parts of the installation are connected to a suitable earth electrode
- see Regulation 411.
Protection in the event of direct contact - Basic Protection.
Doepke RCCBs with a trip rating not exceeding 30 mA, meet the requirements of Regulation 415 based on the
supplementary bonding requirements. Using RCCBs as an additional means of protection does not negate the use
of basic protection methods required under regulation 411.
Fire protection.
Doepke RCCBs with a trip rating not exceeding 300 mA meet the requirements of Regulation 532, however within
the Regulations there are specific requirements where 300mA trip rating may not be appropriate - for example
overhead heating see clause 422.3.9
Types of RCCB required by the IET Wiring Regulations.
In addition to standard RCCBs (Type AC) Doepke manufacture a wide range of devices with specific functions for
different applications.
Please contact us if you require a product that is not listed in our standard documentation.
Type S: used in applications where RCCBs have to be connected in series to achieve discrimination (Fig. 1) between
upstream and downstream devices - see clause 5.31.2.9 and example application 740.411, or 534.2.6 ( Doepke Type
S RCCBs are designed to have immunity to transient wave forms <5kA 8/20µs)
Type A: used in applications with residual sinusoidal alternating currents and pulsating direct currents with a
maximum of 6 mA smooth DC. - see clause 710.411.3.2 and 722.531.2.101
Type B: (IEC 62423) used in applications where in addition
to the above, smooth DC residual currents above 6mA are
present under certain fault conditions - see clause
712.411.3.2.1.2 and 722.531.2.101
Type AKV: used in applications where the RCCB could be
subject to in rush currents < 3000 A , which would cause
tripping of standard RCCB - see clause 534.2.6
Type F: used in applications where the RCCB is subjected
to mixed frequency leakage currents, such as single phase
inverter controlled washing machines, mixers or power
tools.
Type EV: used in electrical vehicle charging applications
where the RCCB must trip if the smooth DC leakage current
exceeds 6mA.

SELECTION & APPLICATION
Operating and Installation Instructions for Residual Current Circuit Breakers DFS2, DFS4
Mounting position: Any position. Installation: By clipping onto DIN EN 50022 rails.
Electrical connections:
Take all phase conductors and the neutral conductor (N) through the switch. The direction of the flow of energy can
be either way, i.e. the mains or the load can be connected to the upper or lower row of terminals. To ensure that the
built-in testing system operates properly
when 4-pole RCCBs are used in 2-pole
applications, use the terminals as per
wiring diagram. Aluminium conductors
must be scraped and greased just
before they are connected up to the
terminals.
Testing:
Testing of the entire protective system
when putting into operation must be
performed
according
to
the
specifications of the valid national
installation regulations. Test quarterly by
pressing the test button T for stationary
equipment and once every working day
for mobile equipment.
Please note that the above fuses provide no overload protection. At the design stage check that the downstream
overload protection does not exceed the total rated current of the RCCB.
Operating Temperature Range:
Doepke RCCBs are calibrated for operation between +40°C to -5°C. For operation down to -25°C the maximum values
of earth fault loop impedance defined in Table 41.5 must be reduced by 20 %.
Voltage Range (Test Circuit Operation)
DFS2 (230V 50Hz) and DFS4 (400V 50Hz) Test circuits will operate down to approximately 50% of the nominal
voltage. For operation on a 110V supply order a 110V unit.
Frequency Range
DFS2 and DFS4 are calibrated to operate on 50 Hz supplies, for any other frequency order a special Doepke RCCB
calibrated for the nominal supply frequency.
General service and warning indications:
Doepke residual current circuit breakers have been carefully tested at several stages of production and have left the
factory in perfect condition witrh regard to safety. To ensure safe operation, please observe the following instructions
and warnings.
1. Installation may only be performed by an authorized electrican, who is acquainted with the relevant
national installation regulations.
2. Residual current circuit breakers without additional protective housings may be stored and operated in
dry, low- dust areas only. Corrosive atmospheres must also be avoided.
3. User´s must be reminded, that all devices should be periodically tested, using the test button T.
4. Trips caused by leakage current due to surge voltage cannot be completely ruled out even with surge
current proof RCCBs. In cases where an interruption in power supply could constitute a hazard to
persons or animals or cause serious damage to property, the earth leakage system should comprise
selective RCCBs with increased surge current strength and over voltage protection. In special cases the
system should be monitored with an auxiliary contact on the RCCBs and a suitable signaling device.
5. If the device is opened the warranty becomes void!

Doepke
A world leader in RCCB design and manufacture Doepke
produces over 2500 different variations of residual current
circuit breakers.
These RCCBs have a contact position indicator, in addition to a reset position, which shows
whether the device has been switched off manually or has tripped due to a fault.
They accept both pin and fork busbar, the pin terminal having a maximum cross-section
of 50mm. There is also a facility to accept a circuit identification label behind a clear
plastic window. The wide range of current values extends from 16 to125 amps in all the
standard sensitivity settings. All these products have been manufactured to BSEN 61008.
All our RCCBs are compatible with our MCB range’s in both size and terminal height.
They also accept our half module auxilary switch which can be retrofitted by the installer.
The terminals will accept a 50mm2 multicore cable thereby facilitating direct connection
to the RCCB. The operating voltage of our RCCBs permits use in 110v circuits.
The type AC RCCBs provide automatic protection in the event of a neutral/earth and
phase/earth fault. The 10mA and 30mA are suitable for the protection of humans, whilst
the 100mA, 300mA and 500mA are used to protect equipment and machinery. The use
of time delay RCCBs enable the contractor to provide several RCCBs with selective
disconnection.

Type
B
For use in 50Hz AC electrical
circuits feeding loads which can
generate AC & DC leakage currents
‘B’ Type RCCBs AC-DC sensitive
Application
Many electrical installations now contain products which
incorporate power electronics, such as inverters for PV
installations, speed control in HVAC, some running machines,
UPS, medical equipment etc. This type of equipment can
produce, in addition to standard 50Hz earth leakage currents,
pure DC and high frequency AC leakage currents which would
not be detected by a standard AC or A type RCCB.
‘B’ type RCCBs in addition to normal AC, can detect high
frequency AC and pure DC earth leakage currents.
Reducing the risk of fire and/or electrocution through automatic
disconnection of the electrical supply (Reg 411), relies on the
selection and installation of the correct type of RCCB.
The IEE Wiring Regs. make specific reference to ‘B’ type RCCBs
(section 712)
