A low voltage high-amp circuit breaker (20) having a substantially rectangular 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.
