  • Circuit breaker
    Patent number: 7310041
    Abstract: The invention relates to a re-settable, single-phase, thermo/electric circuit breaker utilizing a U-shape bimetallic element of substantial resistance properties in the circuit, so that when a predetermined overload current occurs the bimetallic element self heats and moves to trip a mechanism that opens the breaker circuit. The invention replaces the double-contact break configuration normally associated with a breaker of this type, with a single contact break configuration designed to produce a sliding action between contacts during the normal reset operation, providing a more reliable continuity at the moveable and stationary contact interface that is also less expensive to produce.
    Type: Grant
