Square D H-224-NRB Heavy Duty Safety Switch 3R

Square D H224NRB Heavy Duty Safety Switch is a 200 A fusible disconnect designed for 240 V circuits, providing a safe isolation point for motor loads and feeders in industrial environments. This 2-pole, 3-wire unit includes a neutral and arrives in a NEMA 3R enclosure suitable for outdoor or damp locations, with bolt-on hub provisions that support wiring flexibility and future conduit changes. Rated for up to 60 HP at 240 VAC (and compatible with 250 VDC in applicable circuits), it uses per-pole fusing to deliver overcurrent protection and a clear disconnect path at service entrances, pumps, conveyors, and other 240 V equipment. The NRB variant includes a factory-installed neutral connection and mounting provisions that ease installation in exposed environments, while maintaining compatibility with Square D heavy-duty safety switch accessories for durable outdoor performance. Typical applications include outdoor motor disconnects and feeders for electrical distribution panels, as well as protective isolation for pumps, conveyors, and fans in harsh weather environments.
