Schneider Electric FA34070 I-Line Circuit Breaker

Schneider Electric FA34070 I-Line Circuit Breaker is a 3-pole molded‑case protection device rated for 480V AC and 70 amps, designed for integration with Schneider Electric’s I-Line bus systems in industrial panels. As part of the FA family, it provides overcurrent protection for feeders and branch circuits while fitting into standard FA/LA mounting configurations. The I-Line design facilitates fast installation and reliable line-side connections in panelboards and switchgear, with a compact footprint that helps optimize space in crowded electrical rooms. The FA34070 is intended for commercial and light industrial power distribution where a 3‑pole, 480V protection device is needed to guard electrical circuits against overloads and short circuits, while enabling coordinated protection with other FA‑series devices. Typical applications include motor feeders, branch circuits in distribution panels, and equipment protection in warehouses, manufacturing floors, and processing facilities. Key attributes, drawn from Schneider Electric’s FA/MCCB lineup, include a 480V AC rating and 70A current rating with I-Line mounting, built to operate with thermal‑magnetic trip mechanisms that respond to sustained overloads and instantaneous faults. This specific model is ideal when upgrading or replacing an FA‑series MCCB in an I‑Line panel that requires a 70A, 3‑phase, 480V protection solution from Schneider Electric, commonly used alongside other FA or LA molded‑case breakers in centralized distribution schemes.
