Carling Equipment Leakage & Ground Fault Circuit Breakers combine the ground fault protection of a GFCI with the familiar overcurrent tripping characteristics of a normal circuit breaker. PB & PC-Series circuit GFCI breakers range from .10 to 50 amps, and are well suited for Marine industries use as AC branch ground fault protection, AC Main ground fault protection, and portable generator ground fault protection. Carling’s PD-Series Equipment Leakage utilizes state of the art integrated circuit technology to detect faults, and when a fault occurs, the breaker trips and an LED illuminates. The LED gives a clear indication that the trip occurred as a result of leakage. This protection helps prevent serious equipment damage and fire.
