It can be racked to the disconnected position with the cubicle door closed or open.
- Carriage position switch (optional)
- Shutters and padlocking facility
- Contact indication
- Termination: rear (horizontal/vertical)
- Automatic disconnect of secondary circuits
- Easy wiring of the control circuit contacts
- Carrying handles for easy of removing the circuit breaker from the cassette
