How can I design a system that gives the functionality of an MCB (overload protection, operates in an AC circuit) with an electronic trigger-off.
So that once the device is in ON state, it should be able to be turned-off by
Human interaction (mechanically flipping the latch)
Over-load (MCB inherent feature)
Electronically, by using a small trigger voltage. Once this trigger is applied this switch should be mechanically flipped to off position, so that the user should see it is in OFF state.
The device is to be used to run a domestic motor (say 1HP.)
