Features of residual current circuit breakers EFI
Rated conditional
short-circuit current :
10 kA
AC - pure sinus residual current,
A - AC + pulsating direct current
B - AC + A + smooth direct current +
high frequency (1kHz)
Quality seal for B+ - AC + A + smooth direct current +
tested reliability high frequency (20kHz)
Real contact position indica-
tion for easier contact status
identification
Test button enables user to
check residual functionality
Various quality marks
RCCBs can be supplied with
single phase and three phase
busbars
The terminals accept not
only wires but also time saving
busbars
Supply is possible both
from top and bottom terminals

Technical data
Residual current circuit breakers can be used in TN-S, TN-CS, TT and IT network systems, or with other words,
in all systems where neutral and protective conductors are separated. Residual current circuit breakers EFI are
used for protection against indirect contact (fault protection) and direct contact (additional protection) of parts
under voltage. In the case of protection against indirect contact (fault protection) you can use residual current
protective devices with a rated residual current of IΔn ≤ 300mA. Residual current protective devices with a rated
residual current of IΔn ≤ 30mA fulfil the conditions for protection against direct contact (additional protection).
For protection against fire, according to DIN VDE 0100-482 and IEC 60364-4-482, all cables and conductors in
TN and TT systems must be protected by means of residual current protective devices with rated residual current
of IΔn ≤ 300mA. In applications where resistive faults can cause a fire (radiant ceiling heating with panel heating
elements), the rated residual current must be IΔn = 30mA.
Types
AC Type: they are sensitive to alternating (sinusoidal) AC residual currents.
A Type: they are sensitive to alternating (sinusoidal) AC residual currents and pulsating DC residual currents.
B Type: they are sensitive to alternating (sinusoidal) AC residual currents, pulsating DC residual currents and
smooth DC residual currents. Tripping values are defined up to 1kHz.
B+ Type: they are sensitive to alternating (sinusoidal) AC residual currents, pulsating DC residual currents and
smooth DC residual currents. Tripping values are defined up to 20kHz and they are below 420mA.

Auxiliary switch PS EFI
The PS EFI is fixed to EFI series switches. The width of the device is 9 mm, other dimensions are in compliance with EFI
switches. The auxiliary switch PS EFI is used for the remote signalling of the state of contact’s condition (closed/open) of
EFI switches. During fitting, the EFI must be switched off.
