Details
Residual current circuit-breakers, four-pole, 40 A, 0,03 A, Type A, with Operating current trips and Auxiliary switch, N left, HD
Type A residual current circuit-breakers detect pulsating direct current and alternating current. Our ASA RCCB can be remotely tripped by applying an external voltage. The device incorporates an auxiliary contact for remote signalling and an LED for local status indication. In this state, switching back on is prevented. The HD design makes our RCCBs particularly resistant to harmful environmental influences and therefore suitable for harsh environments.
tripping not dependent on mains and auxiliary voltage, sensitive to AC residual currents and pulsating DC residual currents (type A) , compact design for all rated currents, high short-circuit resistance, double-sided two-tier terminals for large conductor cross-section and busbar, switch position indicator, viewing window for labels, multifunction switch toggle with three positions: "on", "off" and "tripped", Neutral conductor position left
quick fastening to mounting rail, any installation position, supply from any direction
Power supplies to residential and purpose-built buildings as well as industrial facilities with TN-S, TT and TN-C-S networks. In IT networks, the residual current circuit-breakers of this series can be set to switch off in the event of a second fault, Excluded is the application in TN-C systems and for the protection of installations in which electronic equipment could generate smooth DC currents or residual currents with frequencies other than 50 Hz. Comprehensive protection is not provided in this case. For these applications we recommend our AC/DC sensitive residual current circuit-breakers (Type B or B+).
