BF120– SIEMENS 1P20A 120V BOLT ON GFCI 10kA BREAKER

The BF120 uses a bolt-on mounting method, securing directly to the panel bus bar with a screw, while the QAF120 clips in as a plug-in breaker. They are not interchangeable — your panel's bus bar design determines which style you need. Check your panel label or send us the model number and we'll point you to the right breaker.

Yes. The BF120 provides Class A GFCI protection (trips at ≤5mA ground fault current), which meets CEC requirements for GFCI-protected circuits in wet or damp locations such as bathrooms, kitchens, garages, and outdoor receptacles. It protects all outlets on the branch circuit, eliminating the need for individual GFCI receptacles downstream.

Availability of specific GFCI breaker models can change over time. Northern Breaker Group specializes in sourcing obsolete and hard-to-find breakers, so even if the BF120 is no longer in regular production we can often locate new-old-stock or suitable replacements. Contact our Calgary, Edmonton, or Vancouver counters for a quote and current stock status.
