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”
? Wiping Contacts - Mechanical linkage with two-step
actuation – cleans contacts, provides high, positive
Agency Certifications:
contact pressure & longer contact life
? A trip-free mechanism, a safety feature, makes it
impossible to manually hold the contacts closed during
overload or fault conditions.
? A common trip linkage between all poles, another safety
feature, ensures that an overload in one pole will trip all
adjacent poles.
? Front panel or DIN rail mounting options
? “State of the art ” integrated circuit developed by Carling
? Equipment leakage sensitivity from 10 to 100 milliamps
? Integral push-to-test button and LED “tripped” indicator
? Immediate reset after fault has been cleared
