AI Technical Summary
In abnormal situations, when the buttons or handles of the existing circuit breaker are locked, the remote tripping command cannot be executed, which causes the moving contact and the stationary contact to be unable to separate, posing a safety hazard.
The electric mechanism employs a trigger and trip unit in conjunction, and the tripping of the tripping and closing drive units is achieved by staggering the trigger operation mechanism. Combined with microswitches and circuit design, current control is ensured in both electric and manual modes, and manual mechanism locking is prevented in abnormal situations.
It enables automatic tripping under abnormal conditions, avoiding the problem of the electric mechanism being unable to trip due to manual mechanism locking, ensuring the circuit breaker trips safely and reliably, and enabling constant switching between electric and manual modes without switching the current mode.
