Why Choose the ABB 1SDA104866R1 RHE_EM XT7 F/W Emergency Returned Rotary Handle?
The ABB 1SDA104866R1 is a genuine emergency adjustable-depth rotary handle operating mechanism for compatible ABB SACE Tmax XT7 moulded-case circuit breakers. Designed for fixed and withdrawable XT7 configurations, it provides a transmitted operating arrangement for controlling the circuit breaker from the front of an enclosure or switchboard.
The RHE_EM mechanism features an adjustable depth of 500 mm and an emergency operating configuration. This arrangement allows the external operating point to be positioned away from the circuit breaker while maintaining mechanical control of the breaker within the assembly.
The 1SDA104866R1 also incorporates a padlock device on the circuit breaker, supporting secure isolation procedures. Its emergency configuration and compatibility with both fixed and withdrawable XT7 installations make it suitable for industrial switchboards requiring accessible, clearly identifiable and lockable circuit-breaker operation.

Secure Emergency Circuit-Breaker Operation
Adjustable-depth rotary handle mechanisms allow a circuit breaker mounted inside an enclosure to be operated from an accessible external control point. The mechanical transmission is particularly useful in switchboards where the breaker position and enclosure door require separation between the circuit breaker and its operating handle.
The ABB 1SDA104866R1 combines this transmitted operating principle with an emergency configuration, 500 mm adjustable depth and padlocking capability. It therefore provides a manufacturer-engineered solution for local emergency operation and secure isolation of compatible SACE Tmax XT7 fixed and withdrawable circuit breakers.
Typical Applications
- ABB SACE Tmax XT7 circuit-breaker installations.
- Fixed and withdrawable XT7 configurations.
- Emergency operating and isolation points.
- Industrial low-voltage switchboards.
- Enclosure-mounted power distribution and protection systems.
- Panel building and OEM switchgear assemblies.
