QOB250GFI - Square D Ground Fault Bolt-On Circuit Breaker

Moisture serves as a conduit for electricity and may cause shock after seeping into electrical appliances. The Square D QOB250GFI 2 Pole Ground Fault Circuit Breaker is designed to address ground faults that are normally found at places where electrical units are exposed to water. This GFCI (Ground Fault Circuit Interrupter) can sense the flow of electricity outside the normal circuit via moisture and into the human body. When it identifies such an incident, it cuts off the electricity by tripping itself and prevents electrocution. It comes with box-type lugs for connecting 14 - 6 AWG copper wires and 12 - 4 AWG aluminum. This CSA certified circuit breaker has voltage, current and interrupting ratings of 120/240 VAC, 50 Amp and 10 kAIC respectively.
