Shunt trip for DRCBO 3

Product description

Operating current trips enable the remote tripping of, e.g. miniature circuit-breakers. The operating current trip is activated by an operating current from an external voltage source. The FAM 1 remote tripping module is a tripping device for residual current operated circuit-breakers with integral overcurrent protection (RCBOs, single-pole+N) as well as for miniature circuit-breakers from series ELS 3. The remote tripping module contains one resistor and one interrupter contact in a 0.5 unit wide, retro-fittable housing. When a voltage of 230 V or 400 V is switched on via the resistor and a tripping current is generated, the residual current operated circuit-breakers with integral overcurrent protection and rated residual currents up to 0.3 A are safely switched off, even when long cable lengths to remote switches or contacts have been laid. Remote switch-off takes place when an external contact is used to switch on a voltage; no remote test is performed. A standard-compliant tripping test is therefore not carried out. After the circuit-breaker trips, the interrupter contact prevents the tripping voltage from being diverted to the consumer system as long as the switch remains closed (safety shutdown).
