The FA26070AB Square D 2P 70A 600/347V breaker is a reliable solution for electrical protection in various applications. Designed for single-phase use, it offers dual pole functionality, ensuring efficient operation and safety. With a robust AMP rating of 70A, this breaker is ideal for both residential and commercial installations.
The FA26070AB uses a bolt-on mounting and is rated for Square D FA-frame commercial and industrial panelboards and switchboards (such as Square D NF-series and I-Line compatible boards). It is not designed for residential loadcentres like QO or Homeline. If you're unsure whether your panel accepts FA-frame breakers, share your panelboard model with us and we'll verify the fit.
Yes — the FA26070AB is rated for 600/347 V AC, making it well-suited for 347 V single-phase branch circuits commonly used in Canadian commercial fluorescent and LED lighting systems fed from a 600 V wye distribution system. Its 18 kA interrupting rating covers most commercial panel locations; confirm your available fault current to ensure adequacy.
