The contacts of the internal contactor could be welded following a downstream short-circuit, in which case it can no longer open the charging circuit. As a result, any DC fault current cannot be removed and the permanent voltage on the socket presents a people safety risk. The Mx/MNx helps to protect people by opening the circuit breaker in this case.
