  • Patent number: 6744345
    Abstract: A circuit breaker includes a base housing comprising a contact cavity therein, first and second terminals at least partially located within said contact cavity, and a thermal trigger element fixedly coupled to said first terminal and in electrical contact with said second terminal in normal operation is provided. The thermal element is configured to activate and break electrical contact with said second terminal upon a predetermined current condition.
    Type: Grant

  • Patent number: 5021761
    Abstract: A low voltage high-amp circuit breaker having a substantially rectangular bimetallic bistable element and a pair of terminals extending from the side thereof. The bistable element is attached to have one end move from a first normal electrically conductive position to a second non-electrically conductive position. The manual reset circuit breaker includes a manual reset lever and a non-conductive heat resistant extension blade connected to the reset lever via a rotatable shaft. The extension blade being positioned adjacent the moveable end of the bistable element and when the element is moved to its second position, the blade is moved to prevent the element from returning to its first conductive position until the circuit breaker is manually reset.

  • Patent number: 5004994
    Abstract: A low voltage high-amp circuit breaker (20) having a substantially reactangular bimetallic bistable element (41). The bistable element is attached to have one end move from a first normal electrically conductive position to a second non-electrically conductive position. The manual reset circuit breaker includes a manual reset lever (29) and a non-conductive heat resistant extension blade (64) connected to the reset lever via a rotatable shaft (56). The extension blade being positioned adjacent the moveable end of the bistable element and when the element is moved to its second position, the blade is moved to prevent the element from returning to its first conductive position until the circuit breaker is manually reset. A push-to-trip button (80) pushes plate (88) downward causing fingers (84) to move upward lifting bracket (92) to deform bistable element (41) placing the breaker in an open circuit condition.
