Abstract
A molded case circuit breaker is described including a U-shaped thermal and magnetic trip assembly pivotally supported by an insulating housing. A compression spring biases the trip assembly against a releasable cradle which is engaged by a latch. The biasing action of the spring against the pivoting trip assembly maintains a constant latch bite despite warping or other mechanical distortion of the insulating housing.
