The PD-Series Smart Guard circuit breaker is an
equipment ground fault protection device that functions as a
standard high-quality Carling Technologies hydraulic/magnetic
circuit breaker , offering customized overload and short
circuit protection. In addition, this breaker senses and
guards against faults to ground using a state of the art
integrated circuit developed by Carling Technologies. This new
technology detects 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.
PD-Series circuit breakers come in 1-3 poles with switched or un-switched neutral options. They have a short circuit interrupt capacity up to 5,000 amps, current ratings up to 50 amps, voltage ratings up to 480VAC, and equipment leakage sensitivity from 7 to 100 milliamps. They offer front panel or DIN Rail mounting options, and are available with handle style actuators with an optional handle guard.
