Schneider Electric FA34015 3-Pole Circuit Breaker

Schneider Electric FA34015 is a three‑pole molded case circuit breaker from the Square D FA/I‑Line family, designed for 480V three‑phase power and rated 15A, with a plug‑on, I‑Line style mounting suitable for compatible panels and switchboards. The unit features a thermal‑magnetic trip mechanism for overload and short‑circuit protection and offers a typical interrupting capacity of 18 kA at 480V, making it capable of safely interrupting fault currents in light to medium‑duty industrial feeders. The FA34015 uses frame type F construction, with a black face, and provides copper or aluminum terminal connections sized 14–4 Cu or 12–4 Al depending on configuration; it is designed for plug‑in installation in FA/MCCB panels that support I‑Line devices. Dimensions are approximately 4.5 in wide, 4.13 in deep, and 6 in high, enabling compact installation where space is at a premium. This model is UL and CSA listed and is intended for use on 480V distribution circuits, including motor feeders, control panels, and other commercial/industrial electrical installations requiring reliable overcurrent protection for 3‑phase loads.
