Abstract
A ground fault accessory for a molded case circuit breaker is provided by converting a shunt trip accessory to automatically trip the breaker when a ground fault occurs. A printed circuit mounted in the housing with the shunt trip eliminates the need for a separate ground fault relay. The ground fault relay and the shunt trip are made available in the same accessory requiring no additional mounting of equipment or external wiring while conserving space which is scarce in load centers and other locations where both ground fault and shunt trip are desired.
