Why Choose the ABB 1SDA054931R1 RHE_B Rotary Handle Base?
The ABB 1SDA054931R1 is an RHE_B base for an adjustable-depth transmitted rotary handle operating mechanism, designed for compatible ABB SACE Tmax T4 and T5 moulded case circuit breakers. It forms part of ABB's RHE transmitted rotary-handle system, allowing the operating mechanism of a circuit breaker mounted inside an enclosure to be linked to an externally accessible rotary handle.
This RHE_B version is specifically designed for fixed and plug-in Tmax T4 and T5 circuit breakers. It is supplied as the base component only, enabling an RHE operating system to be assembled with the appropriate shaft and handle components for the required panel configuration.
The adjustable-depth RHE arrangement is particularly useful where the distance between the circuit breaker and enclosure door varies between installations. The 1SDA054931R1 provides the breaker-mounted base required for this transmitted operating system, making it suitable for switchboards, control panels and industrial distribution assemblies.

- Suitable for enclosed switchboards and distribution assemblies.
- Designed to IEC requirements applicable to the Tmax T accessory system.
Flexible Transmitted Rotary Handle Installation
A transmitted rotary handle system allows a circuit breaker installed inside an electrical enclosure to be operated from a handle positioned on the enclosure door. The arrangement separates the external handle from the breaker-mounted operating mechanism using a transmission shaft, providing installation flexibility where the breaker is recessed within the panel.
The ABB 1SDA054931R1 is the RHE_B base component for this system on compatible Tmax T4 and T5 fixed or plug-in circuit breakers. When combined with the appropriate RHE shaft and handle, it supports an adjustable-depth operating arrangement tailored to the physical dimensions of the switchboard or enclosure.
Typical Applications
- ABB Tmax T4 and T5 fixed circuit breaker installations.
- ABB Tmax T4 and T5 plug-in circuit breaker installations.
- Adjustable-depth transmitted rotary handle assemblies.
- Industrial electrical switchboards and distribution panels.
- Machinery control and power distribution enclosures.
- Commercial and industrial electrical distribution assemblies.
