Square D FHP36040 Molded Case Circuit Breaker

Square D FHP36040 Molded Case Circuit Breaker is a 3-pole, 40-amp MCCB from Square D (Schneider Electric), part of the FH family. Rated for up to 600 VAC, it delivers thermal-magnetic overcurrent protection for three-phase circuits with an 18 kA interrupting rating to handle short-circuit events. This model uses lug-type terminals for secure connections and is designed for industrial and commercial panelboard applications where reliable, space-efficient protection is required for feeders and motor circuits on 3-phase systems. With its 40 A rating, the FHP36040 suits distribution feeders and equipment where moderate continuous load is expected, while remaining capable of interrupting larger faults within its rating. The device supports standard protection schemes within the Square D protection ecosystem, enabling coordination with other FH-frame breakers and compatible enclosures. In essence, the FHP36040 provides a compact, rugged solution for safeguarding three-phase power distribution, motors, pumps, conveyors, and other industrial loads up to 40 A and 600 VAC, combining robust trip characteristics with straightforward terminal connections for quick installation.
