ABSTRACT:
An arrangement for opening a circuit coupled to an electrical power source associated with a neutral circuit. The arrangement includes a bi-stable latch for electrically engaging and disengaging a pair of contacts in response to the value of the sum of currents in the circuit and the neutral circuit exceeding a predefined limit. The arrangement also includes a mechanism for opening and closing a pair of main contacts which are used to open and close the circuit. The mechanism can be operated by a shunt trip solenoid such that the solenoid causes the operating mechanism to open the contacts when the contacts of the bi-stable latch are closed.
