Why Choose the ABB 1SDA104850R1 RHE_EM XT5 W Emergency Returned Rotary Handle?
The ABB 1SDA104850R1 is a genuine emergency returned rotary handle operating mechanism designed for compatible ABB SACE Tmax XT5 withdrawable moulded-case circuit breakers. It provides manual front operation of the circuit breaker while incorporating a returned-handle arrangement for applications where emergency operation and controlled handle positioning are required.
As part of the ABB SACE Tmax XT accessory range, the RHE_EM mechanism is engineered for reliable mechanical integration with the XT5 withdrawable platform. Its emergency configuration provides a clearly identifiable operating interface, while the returned-handle design supports switchboard layouts where the handle is arranged to return after operation.
The 1SDA104850R1 is specifically intended for XT5 withdrawable configurations and combines emergency identification with a returned rotary-handle mechanism. This makes it suitable for low-voltage switchgear where local manual control, emergency isolation and a defined handle-return arrangement are required.

Reliable Emergency Operation and Isolation
Rotary handle operating mechanisms allow moulded-case circuit breakers to be operated manually from the front of a switchboard or enclosure. Emergency versions provide clear identification for isolation duties, while returned-handle mechanisms are used where the operating handle is intended to return to a defined position after actuation.
The ABB 1SDA104850R1 combines these features for compatible SACE Tmax XT5 withdrawable circuit breakers, supporting practical local control and emergency isolation in industrial and commercial low-voltage switchgear.
Typical Applications
- ABB SACE Tmax XT5 withdrawable circuit-breaker installations.
- Emergency electrical isolation points.
- Industrial low-voltage switchboards.
- Power distribution and protection panels.
- Applications requiring a returned rotary-handle arrangement.
- Panel building and OEM switchgear assemblies.
