Siemens 20 amps GFCI Single Pole Circuit Breaker

These circuit breakers offer the new Self-Test and Lockout feature as required by UL 943, enabling the GFCI to automatically and continuously test itself to ensure that it is working properly. If it is detected that the device has been compromised, the device trips itself and locks out the homeowner from resetting the device, reducing the possibility of the homeowner incorrectly assuming that the device was tripped to prevent a ground fault.
