Square D FA36045 Industrial Molded Case Circuit Breaker

Square D FA36045 is a 3-pole molded case circuit breaker (MCCB) rated for 45 amps at up to 600 volts AC, designed to protect three‑phase feeders in industrial power distribution. The FA family from Square D (Schneider Electric) is used in panelboards and switchgear to interrupt fault currents and prevent damage to downstream equipment.

This 45A, 3P unit is suitable for protecting motors, pumps, conveyors, and other equipment in harsh industrial environments, providing reliable overcurrent protection for three‑phase circuits in manufacturing, processing plants, and similar facilities. FA36045 units are part of a broad range of FA‑series breakers designed for modularity and compatibility with other Square D distribution equipment.
