The ABB 1SDA054910R1 is an auxiliary contact module designed for ABB SACE Tmax T-series molded case circuit breakers, specifically compatible with T4, T5, and T6 frame sizes. It features two changeover (SPDT) contacts: one for indicating the circuit breaker's open/closed status and one for fault trip indication. Rated for 250V AC/DC operation, this compact accessory enables remote monitoring and control integration in industrial electrical distribution systems. The module is wired and mounts directly onto the circuit breaker, providing reliable signaling for automation, PLC interfacing, and alarm systems. It supports both new installations and retrofits in motor control centers, switchboards, and industrial control panels.
