The Siemens 3RV1913-7DA00-0FJ0 is an emergency stop handle designed for the 3RV1913 housing. It is a latching type, meaning once actuated it stays in the stop position until manually released by turning the handle. This is a standard interface for lockout/tagout (LOTO) procedures on motor starter and circuit breaker enclosures.
Deployment Context
The latching and turn-to-release mechanism is the operator interface for emergency stop functions on motor starters or circuit breakers in that housing.
