ABSTRACT:
A circuit breaker particularly adapted for use in an oil filled distribution transformer includes an improved bimetal trip actuator which exhibits greater deflection for a given degree of power dissipation. The trip actuator includes a planar bimetal element held relatively stationary at one end and free to deflect at the other end in response to overload current conditions through the circuit breaker. The bimetal element is constructed to have a higher power dissipation in proximity to the stationary end than in proximity to the deflecting end.
