Ground Fault Circuit Protection
SmartGuard is an equipment ground fault protection device
that functions as a standard high-quality Carling 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. 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.
Features:
Overload, short circuit and ground fault protection in a
single package
Handle style actuators with optional handleguard
