Schneider Electric FA34070 ILine Circuit Breaker

Schneider Electric FA34070 is a three‑pole molded‑case circuit breaker from the FA family, rated for 70 A at 480 VAC and designed for use with Schneider Electric’s I‑Line protection system in three‑phase panels. It uses a thermal‑magnetic trip mechanism to provide overload protection and short‑circuit interruption, and it features a line‑side I‑Line connection with load‑side lugs capable of accepting 14–1/0 AWG aluminum or copper conductors. In catalog data, FA34070 variants are listed with a short‑circuit interrupting rating up to 18 kA at 480 VAC, making it suitable for feeder and motor‑circuit protection in commercial and light industrial settings. Schneider Electric discontinued FA34070 on November 11, 2020, with replacement guidance pointing to the PowerPacT B family (for example BDA36070) as the modern equivalent, and service (spare parts, repairs) continuing beyond that date where available. This FA34070 model was commonly used in distribution panels that require a compact, plug‑in I‑Line breaker for 480 VAC systems, delivering reliable, code‑compliant protection for downstream equipment.
