The SIEBF120H – Siemens 1P 20A 120V GFCI Breaker features a compact design with a robust 22 KAIC rating for reliable short-circuit protection. Ideal for residential and commercial applications, this breaker ensures safety in wet environments. Upgrade your electrical system with this high-performance GFCI breaker for enhanced protection and peace of mind.
The 'H' suffix on the BF120H denotes a higher interrupt rating — 22 KAIC (kilo-ampere interrupting capacity) compared to the standard 10 KAIC on the BF120. If your panel or local electrical code requires a 22 KAIC rating, the BF120H is the correct choice. Always verify the required AIC rating for your specific installation before selecting a breaker.
Yes — that's exactly what this breaker is designed for. The BF120H provides Class A GFCI protection (trips at 5mA ground-fault current), making it code-compliant for wet or damp locations such as bathrooms, kitchens, garages, and outdoor circuits as required by the Canadian Electrical Code (CEC). It protects all downstream outlets on the circuit, so a separate GFCI receptacle at each location is not required.
Siemens has transitioned some BF-series GFCI breakers over the years, and availability through standard channels can be limited. Northern Breaker Group specializes in hard-to-find and obsolete breakers — if the BF120H is out of stock locally, we can typically source it through our network. Contact our Calgary, Edmonton, or Vancouver counter or request a quote online and we'll confirm availability for you.
