Electromechanical Interlock For Electrical Protection Devices

摘要

An interlock is presented which may be mechanically interconnected with a circuit breaker. The interlock (10) toggles between a locked out position that causes the circuit breaker to trip and prevents closure thereof and a non-locked out position wherein the circuit breaker functions. The interlock includes a frame (12), a lockout actuator (44) supported by the frame, a reset actuator (48) also supported by the frame and a latching assembly (42). The latching assembly includes a lockout lever (46) that is responsive to movement of the lockout actuator that is pivotably supported by the frame and a lockout trip rod responsive to movement of the lockout actuator. Also provided is a reset lever (50) that is responsive to movement of the reset actuator and that is also pivotably supported by the frame. The reset lever is configured to prevent movement of the lockout actuator without movement of the reset lever and wherein the lockout trip rod is configured for movement between a locked out position and a non-locked out position.
