Function
CBRs (circuit-breakers with integral residual current protection) are circuit-breakers with a magnetic and thermal overcurrent trip and
a residual current trip. The circuit-breaker with residual current trip is used for overcurrent protection of equipment, cables and lines in
accordance with DIN VDE 0100-430 and for protection against electrical shock by automatic switch-o of the power supply as per DIN
VDE 0100-410. This series contains compact devices for rated currents up to 250 A with integrated auxiliary switch and terminals for
large cable cross-sections. The devices are preferably mounted on a mounting plate. Switches with residual current characteristic A are
independent of the mains voltage and allow the detection of sinusoidal AC currents and pulsating DC residual currents. Switches of this
variant have a xed residual response current of 30 mA for the protection of persons. They therefore provide fault and re protection as
well as additional protection (personal protection, protection in the event of direct contact). Devices in the standard design are intended
for monitoring circuits with a rated voltage of 230 V or 400 V and a rated frequency of 50 Hz or 60 Hz.
Features
xed rated residual current of 0.03 A, type range with rated currents from 100 A to 250 A, four-pole, rated voltage 400/690 V AC, detection
of AC residual currents and pulsating DC residual currents (type A as per IEC TR 60755), function range of the residual current trip 0-690 V,
function range of the residual current operated protective device 280-690 V, trip independent of the mains voltage and auxiliary voltage
when overcurrent and residual currents occur , high short-circuit switching capacity, terminals up to 185 mm², , high surge current
strength, i.e. low tendency to faulty trips due to transient residual currents, thresholds adjustable for instantaneous and slow-blow
overcurrent trip, integrated auxiliary switches
Mounting
mounting on mounting plate, any installation position, supply from any direction
Applications
power supplies to purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks with high short-circuit power
, In IT networks, the residual current trip of the CBR can be set to switch o in the event of a second earth fault.
, use for residual current protection in TN-C networks is excluded
Notes
The type A CBR does not provide comprehensive protection in systems containing electronic equipment can cause smooth DC residual
currents or residual currents with frequencies not equal to 50 Hz. For these applications we recommend our AC/DC sensitive CBR type B.
