Schneider Electric FH36045 molded-case circuit breaker, a 3-pole, 45 A device rated for up to 600 VAC, belongs to the Square D FH family. This thermal-magnetic MCCB uses I-Line plug-in mounting for panel installations, delivering overcurrent protection for 3‑phase circuits in industrial control panels. Typical applications include protecting motors, pumps, conveyors, and other heavy loads in commercial or light-industrial electrical systems that operate at 600 V. As a legacy FH-series breaker, it matches panel designs that require FH/I-Line form factor and plug-in compatibility.
