The FKA160301 Square D 1P 30A 347V A PH I Line circuit breaker is designed for reliable performance in various electrical applications. This single-pole breaker ensures optimal safety and protection, handling 30 amps at 347 volts. Perfect for commercial and industrial settings, it guarantees peace of mind with its robust design and efficiency.
I-Line is Square D's proprietary plug-in system where the breaker connects directly to the bus via a stab (plug-in) connection rather than bolting on. The FKA160301 must be installed in a Square D I-Line compatible panelboard or switchboard. It will NOT fit QO or Homeline loadcentres. Send us your panelboard model and we'll verify compatibility.
Yes — 347V is a standard voltage in Canadian commercial and industrial electrical systems, arising from a 600V three-phase wye distribution (600V ÷ √3 ≈ 347V). This makes the FKA160301 specifically suited for Canadian single-phase branch circuits fed from 600V wye systems, which is common in commercial buildings across Canada.
The Square D FKA I-Line frame series can be difficult to source through standard supply channels, particularly for specific voltage and interrupt ratings like this 347V / 65kA unit.
