50 amp thermal circuit breaker
How does a thermal circuit breaker work?
The heart of the thermal circuit breaker is the KLIXON® metal disc. At a predetermined overload, the heat caused by current passing through the disc causes the disc to reverse its curvature, or snap. This snapping action separates the electrical contacts and opens the circuit.
What is the minimum size of a circuit breaker?
Note: Minimum Circuit size is #12 with 20 Amp CB. Circuit Breaker Size 2. Maximum loading of any circuit breaker is 80% of rating for non-motor loads with exceptions as noted below. Breaker cannot be larger than ampacity of wire, except for motors and a few other loads.
Who are the largest manufacturers of circuit breakers?
With four ISO registered manufacturing facilities and technical sales offices worldwide, Carling now ranks among the world’s largest, privately owned manufacturers of hydraulic magnetic circuit breakers, thermal circuit breakers, electrical
