Why Choose the ABB 1SDA104864R1 RHE_B XT7 F/W Rotary Handle Base?
The ABB 1SDA104864R1 is a genuine base for an adjustable-depth rotary handle designed for ABB SACE Tmax XT7 circuit breakers. Designated RHE_B XT7 F/W BASE R.DIST.ADJ.ROT.HA, it forms the breaker-side base of a transmitted rotary operating system for compatible fixed and withdrawable XT7 installations.
As part of the ABB SACE Tmax XT manual operating accessory range, the RHE_B base provides the mechanical interface between the XT7 circuit breaker and the remaining components of an adjustable-depth rotary handle system. This allows the breaker to be operated remotely from an enclosure door or operating panel when combined with the appropriate ABB handle and transmission components.
The 1SDA104864R1 is specifically designed for fixed and withdrawable XT7 circuit breakers. Supplied as the base component rather than a complete rotary handle assembly, it provides an ABB-engineered foundation for professional enclosure-mounted operating systems in industrial switchboards and low-voltage distribution equipment.

Adjustable-Depth Rotary Operation for Tmax XT7
A transmitted rotary handle system allows a circuit breaker mounted inside an enclosure to be operated from a remote position, typically at the switchboard door. The ABB 1SDA104864R1 provides the breaker-side RHE_B base required to connect a compatible XT7 to this type of adjustable-depth operating system.
This base is suitable for both fixed and withdrawable XT7 circuit-breaker configurations. It is intended to be combined with the appropriate ABB RHE handle and transmission components, allowing panel builders to configure the complete rotary operating arrangement to suit the enclosure design.
Typical Applications
- ABB SACE Tmax XT7 fixed circuit breakers.
- ABB SACE Tmax XT7 withdrawable circuit breakers.
- Adjustable-depth transmitted rotary handle systems.
- Industrial low-voltage switchboards and switchgear.
- Enclosure-mounted circuit-breaker operating controls.
- OEM power distribution and industrial control assemblies.
