The FA17030A Square D 1P 30A 347V A PH I Line circuit breaker is designed for reliable and efficient protection in your electrical systems. With a 30A capacity and 347V rating, this breaker ensures optimal performance for various applications, including commercial and industrial settings. Ideal for enhancing safety and circuit integrity.
The FA17030A uses Square D's I-Line plug-in mounting style, so it is designed for Square D I-Line commercial and industrial panelboards and switchboards. It is not compatible with Square D QO or Homeline residential loadcentres. If you're unsure whether your panelboard accepts I-Line plug-in breakers, send us the panelboard model number and we'll verify compatibility.
The 347V rating corresponds to the phase-to-neutral voltage of a 347/600V distribution system, which is the standard commercial and industrial supply voltage used across Canada. This makes the FA17030A the correct choice for single-phase 347V branch circuits in Canadian commercial buildings, rather than a standard 120/240V residential breaker.
Availability of specific FA-frame breakers can vary — some variants are still manufactured while others have become hard to find. Northern Breaker Group specialises in obsolete and hard-to-find breakers and maintains extensive inventory across our Calgary, Edmonton, and Vancouver locations.
