Why Choose the ABB 1SDA054935R1 RHE_B Rotary Handle?
The ABB 1SDA054935R1 is an RHE_B adjustable extended rotary handle operating mechanism designed for compatible ABB SACE Tmax T4 and T5 moulded case circuit breakers. Identified as RHE_B T4-T5 W SIDE B.R. DIST. ADJ. ROT., this genuine ABB accessory provides remote mechanical operation of the breaker from an enclosure or switchboard door.
The RHE_B arrangement is designed for installations requiring an adjustable rotary operating mechanism with side breaker operation. It transfers the operator's rotary movement from the external handle to the internally mounted circuit breaker, allowing the breaker to be operated while remaining enclosed within the electrical panel.
Designed specifically for ABB Tmax T4 and T5 circuit breakers, the 1SDA054935R1 supports flexible switchboard layouts where the breaker position and enclosure-door operating point require a dedicated extended mechanism. Its ABB-engineered construction provides coordinated mechanical integration with the compatible Tmax platform.
Key Advantages
- Genuine ABB SACE Tmax extended rotary handle accessory.
- Provides external mechanical operation of an enclosed circuit breaker.
- Adjustable rotary mechanism supports flexible panel layouts.
- Designed for side breaker operation.
- Compatible with ABB Tmax T4 and T5 circuit breakers.
- Suitable for switchboard and enclosure-door operating applications.
- Manufacturer-engineered for coordinated integration with ABB Tmax equipment.
Key Features
- ABB SACE Tmax T accessory.
- RHE_B extended rotary handle configuration.
- Adjustable rotary operating mechanism.
- Designed for side breaker operation.
- Compatible with Tmax T4 and T5 breaker frames.
- Suitable for enclosure-door operation.
- Provides mechanical transfer of rotary movement to the circuit breaker.
- Suitable for industrial low-voltage distribution assemblies.
Adjustable External Operation for Tmax T4 and T5
An extended rotary handle allows an internally mounted circuit breaker to be operated from outside its enclosure. The operating mechanism mechanically transfers movement between the door-mounted handle and the breaker, providing convenient access while the switchboard or control-panel enclosure remains closed.
The ABB 1SDA054935R1 adds an adjustable rotary arrangement with side breaker operation for compatible Tmax T4 and T5 installations. This makes it particularly useful where enclosure dimensions, breaker positioning or switchboard geometry require flexibility in the mechanical operating arrangement.
Typical Applications
- ABB Tmax T4 and T5 circuit breaker installations.
- Industrial low-voltage switchboards.
- Enclosure-door circuit breaker operation.
- Control panels with side-operated breaker arrangements.
- Machine electrical panels.
- Power distribution cabinets requiring an adjustable rotary mechanism.
