Circuit-breakers with integral residual current protection, 4-pole, 100 A, Type A, adjustable

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. Type A switches are sensitive to pulsating and alternating currents. This function is independent of the mains voltage. For switches of this variant, the residual response current can be individually set in levels for the application in question (0,3 A, 0,5 A, 1 A, 3 A). The non-response lag time can also be adjusted in levels accordingly. Selective residual current circuit-breakers are therefore possible in systems with stacked distribution boards. Standard variant devices are designed for the monitoring of circuits with a rated voltage of 400 V/690 V and a rated frequency of 50 Hz.

adjustable rated residual current , 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 , thresholds adjustable for instantaneous and slow-blow overcurrent trip , integrated auxiliary switches

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

stacked power supply systems with TN-S, TT, and TN-C-S networks with high short-circuit performance in purpose-built buildings and industrial facilities , 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.
