Why Choose the ABB RHE_EM T7 F/W Emergency Returned Rotary Handle?
The ABB 1SDA062123R1 is an extended emergency rotary handle operating mechanism designed for ABB SACE Tmax T7 circuit breakers in fixed and withdrawable configurations. Identified as RHE_EM T7 F/W EMER. RETURNED, it provides external rotary operation of a compatible breaker when installed inside a switchboard or electrical enclosure.
As part of the ABB SACE Tmax T4–T8 accessory range, the RHE_EM mechanism is intended for installations requiring an emergency-style operating handle and extended operation from the enclosure door. The mechanism transfers the operator's rotary movement to the breaker operating mechanism while allowing the circuit breaker itself to remain safely mounted inside the assembly.
The 1SDA062123R1 is specifically configured for ABB Tmax T7 fixed and withdrawable circuit breakers and uses an emergency returned handle arrangement. It is suited to industrial and commercial switchboards where accessible external circuit-breaker operation and clear emergency-control functionality are required.

Reliable External Operation for ABB Tmax T7 Circuit Breakers
An extended rotary handle allows a circuit breaker installed inside an enclosure to be operated from the exterior of the switchboard. The mechanism mechanically transfers movement from the external handle to the breaker, providing convenient switching access without requiring direct operation of the circuit breaker inside the panel.
The ABB 1SDA062123R1 combines this extended operating arrangement with an emergency returned handle configuration. Its dedicated Tmax T7 design makes it suitable for fixed and withdrawable installations where external operation and clearly identifiable emergency switching functionality are required.
