REF.NO: FKM2462
The ABB 1SDA051368R1 is a changeover auxiliary contact module designed for use with ABB SACE Tmax moulded case circuit breakers (MCCB) across the T1, T2, T3, T4, T5, and T6 frame series. It provides simultaneous open and closed position signalling combined with a dedicated changeover contact for tripped indication — making it essential for remote monitoring and protection coordination in marine main switchboards, distribution panels, and power management systems. Accurate breaker status feedback is critical onboard for fault isolation, alarm triggering, and load management.
Key Features
