The Susol circuit breaker can offer protection against earth leakage currents by using an add-on residual current device (RCD).In particular, the 4-pole versions of TS100, TS160 and TS250 MCCBs can be combined with the RTU24 of residual current device. The RCD unit interfaces directly below the circuit breaker trip unit area without the use of any secondary wiring or connections.

● For use with Susol MCCB with 4-pole● Alarm contact (FAL-fault alarm switch) to

remotely indicate tripping due to an earth leakage current.
