Emergency Manual Operation for ABB Tmax XT7 Circuit Breakers
A direct rotary handle provides a mechanical interface for operating a moulded-case circuit breaker directly from its front face. Unlike a transmitted rotary handle arrangement, the direct mechanism does not require an extension shaft, making it a practical solution where operation is required directly at the breaker within a switchboard or electrical assembly.
The ABB 1SDA104840R1 combines direct XT7 operation with a red/yellow emergency configuration and padlock facility. This allows the breaker operating mechanism to be clearly identified and secured against unauthorised operation when required, supporting controlled isolation and emergency switching practices in industrial electrical installations.
Typical Applications
- ABB SACE Tmax XT7 moulded-case circuit breaker installations.
- Emergency switching and isolation applications.
- Industrial low-voltage switchboards.
- Fixed and withdrawable XT7 circuit breaker assemblies.
- Power distribution panels requiring padlockable manual operation.
- OEM switchgear and industrial electrical equipment.
