Residual Current Device for Moulded Circuit Case Breakers – Ultimate Protection against Earth Leakage Currents for Plant and Personnel

The Susol moulded case circuit breaker (MCCB) from LSis can offer protection against earth leakage currents by an add-on residual current device (RCD) which interfaces directly below the circuit breaker trip area without any additional wiring or connections.

The RCD units have numerous adjustable current sensitivity and time delay settings, together with integrated test and reset buttons for functionality testing.  The range can be integrated in the 2 and 3 pole Susol MCCB’s up to 690VAC and 800A.  The RCD unit can also be equipped with an optional alarm switch for remote indication of earth leakage trips.

The RTU range of RCD together with the reliable Susol MCCB are the perfect combination for your earth leakage requirements in mining and industry.
