Siemens QF250A Breaker Ground Fault Circuit Interrupter, 50 Amp, 2 Pole, 240 Volt, 10,000 AIC

Siemens GFCI circuit breakers are UL Listed and CSA Certified as Class A devices. These circuit breakers offer the new Self-Test and Lockout feature as required by UL 943, enabling the GFCI to automatically and frequently test itself to make certain that it is working properly. Whether it is detected that the device has been compromised, the device trips itself and locks out the homeowner from resetting the device, reducing the opportunity of the homeowner incorrectly assuming that the device was once tripped to prevent a ground fault. Compatible with Siemens load centers rated to accept QPF type breakers. Note: A load neutral isn’t required on the circuit. On the other hand, the white line neutral (pigtail) should be connected to the panel neutral for the device to function.
