Siemens Q220AFCWG Circuit Breakers TCB9N_DT019

Product details:

Siemens AFCI 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 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. For use in standard ES, PL, eq, or ultimate Siemens series load centers, use the catalog numbers without the WG at the end.
