Schneider Electric FA3408010 Three-Phase Circuit Breaker

Schneider Electric FA3408010 Three‑Phase Circuit Breaker is an 80 A, 3‑pole unit designed for 220–240 V AC distribution. Often labeled as Square D FA3408010, this component belongs to Schneider Electric’s FA family of molded‑case breakers and is intended for three‑phase protection in a single enclosure. The FA3408010 configuration is used to guard three live conductors in commercial and light industrial panels, helping to prevent damage to wiring and equipment from overcurrents and short circuits. With an 80 A rating, it suits feeders and branch circuits that operate near 240 V and require reliable interruption of fault currents across all three phases. This model is commonly employed in control panels, machine installations, and distribution boards where three‑phase power is distributed at roughly 240 VAC, ensuring synchronized disconnection of all phases when abnormal currents are detected. As part of the Schneider Electric FA line, it integrates with compatible Schneider Electric enclosures and accessories, enabling straightforward replacement and consistent performance within FA‑series installations.
