摘要:
The thermal circuit breaker and switch has fixed and movable contacts, and non-conductive contact and trip actuators. The movable contact is provided on the free end of a lever arm that normally biases the movable contact toward its open position. The contact actuator transfers movement from a rocker or operator to the movable contact arm when no overload condition exists. The trip actuator is L shaped and rotates in a socket when engaged by a thermally sensitive bi-metallic element so as to allow one end of the contact actuator to float freely, allowing the movable contact arm's bias to open the circuit. The bi-metallic element is so positioned as to engage and rotate the trip actuator only when the bi-metallic element is deformed due to an overheat condition that occurs with an overcurrent. A compression spring acts between the upstanding legs of the trip actuator and the underside of the rocker thus biasing the rocker to the `off` position and biasing the trip actuator to the `reset` position. The rocker employs hooks or posts to engage and position the contact actuator to the reset position after being tripped or manually switched off.
