The GE Q-line 50 Amp 1 in. Single-Pole Circuit Breaker has a dedicated calibration screw which is cemented to prevent shifting. The attached screw creates a stable calibration for optimum performance. The unit has a tin-plated copper stab to create a reliable, permanent and corrosion-resistant connection. The breaker case is made of heat-resistant thermoset for stability and structural integrity.
The GE 20 amp Double Pole Ground Fault Circuit Breaker with self-test has a tin plated copper stab to create a reliable, permanent and corrosion resistant connection. The self-test functionality is a UL requirement on all GFCI devices commencing in June 2015. This variant of the GFCI ensures its ground circuitry is functioning properly by automatically running diagnostic testing on a periodic basis. Should a problem be detected, the circuit breaker will trip and will need to be replaced.
Q line circuit breakers are one-inch wide per pole, compact, thermal-magnetic devices designed for residential and commercial applications. The QL breakers are plug-in versions of the Q Line used for connection to load centers and lighting panels. All Q Line circuit breakers feature Quick-make/Quick-break mechanisms, common trip bars and easy to spot trip indication to ensure safety and reliability. Q Line breakers are available in 1, 2 and 3 pole versions, can be ordered with auxiliary contact and shunt trip accessories and can be ordered for use in HID applications.
