The FA14015A Square D 1 Pole 15A 277V A PH I Line circuit breaker is designed for superior performance and reliability in various electrical applications. This compact breaker provides essential protection against overloads and short circuits, ensuring the safety of your equipment. Ideal for residential and commercial settings, it’s a dependable choice for your circuit protection needs.
The FA14015A is an FA-frame molded-case circuit breaker (MCCB) rated for 277V commercial and industrial panelboards that accept Square D FA-frame plug-in breakers. It is not designed for residential QO or Homeline loadcentres. Contact us with your panelboard model number and we'll confirm the fit.
Availability can vary as Square D updates its product lines over time. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the FA14015A is no longer in current production, we can often source genuine stock. Reach out to one of our Calgary, Edmonton, or Vancouver counters for availability.
The 277V rating is standard for commercial lighting circuits fed from a 480Y/277V three-phase system, where each phase-to-neutral voltage is 277V. This means the FA14015A must only be installed in a panelboard supplied by a 480Y/277V source — it should never be used on a 120/240V residential system. Always verify your supply voltage and panelboard rating match before installation, and consult a licensed electrician to ensure compliance with the Canadian Electrical Code.
