BRYANT 2021 Full Line Catalog (BC003 1/21)

Ground Fault Devices

GFCI Sensing Modules

• In the event of a ground fault, the load is interrupted by way of the hydraulic magnetic circuit breaker utilizing a shunt trip coil • Automatic or manual “safe start” reset feature • Rated from 1 to 50 amps • Ideal for portable generator integration protecting all outlets on a generator • Achieves a NEMA 4X Rating when mounted with the supplied gasket • Meets the proposed requirements for generators Underwriters Laboratory subject 2201, UL/cUL 943 Listed, Class A 4-6mA trip level and UL 1053 Compliant
