Why Choose the ABB 1SDA104831R1 RHD_EM XT5 Emergency Direct Rotary Handle?
The ABB 1SDA104831R1 is an RHD_EM emergency direct rotary handle operating mechanism designed specifically for ABB SACE Tmax XT5 withdrawable circuit breakers. It provides direct manual operation of the circuit breaker while offering a distinctive emergency operating interface for industrial switchboards and low-voltage distribution equipment.
Part of the ABB SACE Tmax XT operating mechanism accessory range, the RHD_EM is the emergency version of the direct-mounted rotary handle. Its red/yellow operating handle provides clear visual identification for emergency operation, while the integrated padlocking facility allows the mechanism to be secured when required as part of established electrical isolation procedures.
The 1SDA104831R1 mounts directly to a compatible XT5 withdrawable circuit breaker, eliminating the need for an extension shaft associated with transmitted rotary handle arrangements. It is suitable for emergency-stop applications and is manufactured for use with ABB's XT5 moulded-case circuit-breaker platform.
