Compliance and Restrictions



Miniature circuit breaker with ground fault protection provides load level detection that isolates only the affected circuit when a ground leakage occurs. Applying a branch breaker with integral ground fault protection allows users to quickly identify the ground leakage’s current location and address the problem before it escalates to hazardous levels. Breaker also provides enhanced protection of a system’s wiring and sensitive electronic components. Low levels of fault current can injure or harm personnel and damage sensitive electronic equipment yet remain insufficient to operate the thermal-magnetic functions of the circuit breaker.
