Schneider Electric FAL34040 Molded Case Circuit Breaker

Schneider Electric’s FAL34040 Molded Case Circuit Breaker is a three‑pole protection device designed for 480‑volt electrical distributions, rated at 40 A to safeguard feeders from overloads and short circuits in industrial and commercial installations. As part of Schneider Electric’s FA/LA/FAL family of molded‑case breakers (Square D by Schneider Electric), the FAL34040 provides thermal‑magnetic overcurrent protection for three‑phase circuits and is specified for up to 18 kA interrupting capacity at 480 V, enabling it to interrupt fault currents safely in typical building and facility power systems. The compact MCCB format combines robust enclosure characteristics with termination options suitable for panelboard installations, making it a common choice for service entrances, motor feeders, and distribution panels handling up to 40 A. The FAL34040 is one of Schneider Electric’s legacy references that aligns with standard 3‑phase, 480 V protection schemes in industrial controls, supporting coordinated protection with upstream devices and other protective relays in larger power distribution schemes. For applications requiring reliable overcurrent protection in a 3‑phase 480 V network—whether in manufacturing, data centers, or large commercial facilities—this 40 A MCCB from Schneider Electric offers a proven combination of interrupting capacity, trip characteristics, and compatibility with the broader Schneider protective devices ecosystem.
