1SDA054932R1 ABB T4-5 RHE-S 500 mm Rotary Handle Rod

Why Choose the ABB 1SDA054932R1 T4-5 RHE-S 500 mm Rod?

The ABB 1SDA054932R1 is a genuine RHE-S 500 mm operating rod for adjustable-depth rotary handles used with ABB SACE Tmax moulded case circuit breakers. Also identified as T4-5, this accessory forms part of ABB’s transmitted rotary handle operating mechanism system and is designed to connect the circuit breaker mechanism to a remotely mounted rotary handle.

The rod allows the operating handle to be positioned away from the circuit breaker, making it particularly suitable for switchboards, control panels and electrical enclosures where the external handle is mounted on the cabinet door. Its adjustable-depth arrangement helps accommodate different enclosure layouts while providing reliable mechanical operation of the breaker.

With a nominal rod length of 500 mm and an approximately 10 × 10 mm cross-section, the 1SDA054932R1 is designed for ABB Tmax T rotary handle assemblies including T4 and T5 circuit breaker applications. It is supplied as the RHE-S rod component only, allowing it to be combined with the appropriate RHE base and handle components for the required installation.

Reliable Remote Operation for Tmax Circuit Breakers

Transmitted rotary handle mechanisms allow a moulded case circuit breaker to be operated from the exterior of an electrical enclosure. The operating rod mechanically links the breaker-mounted mechanism to the external handle, enabling convenient switching while the circuit breaker remains installed inside the panel.

The ABB RHE system is designed for dependable integration with SACE Tmax circuit breakers. The 1SDA054932R1 RHE-S rod provides the mechanical connection required for adjustable-depth installations and can be combined with the appropriate ABB RHE base and rotary handle components to create a complete operating mechanism.

Typical Applications

• Industrial electrical distribution panels.
• Low-voltage switchboards and switchgear assemblies.
• Machine control cabinets.
• Motor control and automation panels.
• OEM electrical enclosures.
• Remote operation of ABB Tmax T4 and T5 circuit breakers.
