  • Thermal circuit breakers
    Patent number: 3991395
    Abstract: A thermal circuit breaker includes a movable contact assembly which is held in an operative position against a fixed contact assembly by means of a catch movable by means of a temperature sensing device which is responsive to the current flowing between the contacts. When this current exceeds a predetermined value the catch is released and the contacts move to the open position. A manually operable control is provided to effect resetting of the circuit breaker and it is additionally operable to effect opening of the contacts when it is required to stop current flow through the circuit which is protected by the breaker.
