Square body profile originally made by Federal Pacific Electric, then Challenger, then Federal Pioneer and American Circuit Breaker. Typically used in schools or commercial applications, but rarely for homes. Bolt on type breakers are for commercial applications where power demand is constant and eliminates buss arcing. First color available will be shipped. Breakers were also made in the past by Federal Pioneer, American Circuit Breaker Co. and a knock off by Connecticut Breaker Co. which presently holds the rights to the brand name. This newer model has the plastic hump over the lugs.
