Circuit-breakers with integral residual current protection, 4-pole, 125 A, 0,03 A, Type A

Circuit-breakers with residual current trip (CBR) switch high currents, protect equipment, cables and lines against overcurrent and protect people against electric shock. DFL 8 are compact devices with integrated auxiliary switch and terminals for large conductor cross-sections. The devices are preferably mounted on a mounting plate. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage.Type A residual current circuit-breakers are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. Switches of this variant have a fixed residual response current of 30 mA for the protection of persons. They therefore provide fault and fire protection as well as additional protection (personal protection, protection in the event of direct contact). Devices in these special versions are designed for monitoring electric circuits with a rated voltage that differs from 400 V/ 690 V and/or a rated frequency that differs from 50 Hz.

fixed 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, 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 on mounting plate, any installation position , supply from any direction

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 off in the event of a second earth fault. , use for residual current protection in TN-C networks is excluded

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.
