Why Choose the ABB 1SDA104849R1 RHE_EM XT5 Emergency Transmitted Rotary Handle?
The ABB 1SDA104849R1 is an RHE_EM emergency transmitted rotary handle operating mechanism designed for compatible ABB SACE Tmax XT5 fixed circuit breakers. It enables the circuit breaker to be operated from the front of an enclosure or switchboard door while the breaker itself is mounted inside the assembly.
Part of the ABB SACE Tmax XT operating mechanism accessory range, the RHE_EM is the emergency version of the transmitted rotary handle system. It provides a clearly identifiable operating interface for applications where emergency circuit-breaker operation is required, while the transmitted arrangement allows the external handle to operate the internally mounted breaker through the associated mechanism.
The 1SDA104849R1 is specifically configured for XT5 fixed (F) installations and uses a returned / transmitted operating arrangement. This makes it suitable for industrial switchboards, machinery panels and power distribution enclosures where the breaker must remain inside the cabinet while its operating control is accessible from the enclosure exterior.
Key Advantages
- Genuine ABB SACE Tmax XT5 operating mechanism accessory.
- Emergency transmitted rotary handle for enclosure-door operation.
- Designed specifically for XT5 fixed circuit breakers.
- Provides remote mechanical operation of an internally mounted circuit breaker.
- Emergency configuration provides clear differentiation from standard operating handles.
- Purpose-designed for integration with the ABB SACE Tmax XT platform.
Key Features
- ABB SACE Tmax XT accessory range.
- RHE_EM emergency rotary handle mechanism.
- XT5 frame compatibility.
- Designed for fixed (F) circuit-breaker configurations.
- Transmitted / returned operating arrangement.
- Enables circuit-breaker operation from an enclosure or switchboard door.
- Designed for emergency operating applications.
- Suitable for industrial low-voltage switchgear assemblies.
Reliable Emergency Operation for Enclosed XT5 Circuit Breakers
A transmitted rotary handle allows a circuit breaker installed inside an electrical enclosure to be mechanically operated from the enclosure door. Movement of the external rotary handle is transferred to the breaker mechanism, giving operators convenient access to switching and isolation functions without requiring direct access to the circuit breaker itself.
The ABB 1SDA104849R1 combines this transmitted operating principle with an emergency-handle configuration for compatible SACE Tmax XT5 fixed installations. It is therefore particularly suited to machinery, industrial distribution and switchboard applications requiring an externally accessible emergency operating interface.
Typical Applications
- ABB SACE Tmax XT5 fixed circuit breakers.
- Industrial low-voltage switchboards.
- Emergency circuit-breaker operating arrangements.
- Machinery electrical control panels.
- Power distribution and protection enclosures.
- Door-operated circuit-breaker installations.
