Eaton 1HD363NF NEMA 1 Indoor Safety Switch 600 VAC

Eaton Cutler-Hammer 1HD363NF is a 3-pole safety switch rated for 100 A, engineered to safely disconnect 3-phase power in indoor environments up to 600 VAC. The unit is housed in a NEMA 1 enclosure, designed for indoor, dry locations and offering basic protection against dust and incidental contact, making it well-suited for control panels, machinery disconnects, and general equipment isolation in commercial or light-industrial facilities. With a 3-pole configuration, the switch provides three separate current paths aligned with typical 3-phase distribution, and its 100 A rating defines the maximum current it is intended to handle, while the 600 VAC rating defines the maximum voltage of circuits it can safely disconnect. The part number 1HD363NF identifies this specific Eaton safety switch within the Cutler-Hammer family, enabling compatibility with Eaton mounting footprints and accessories, and offering a reliable indoor disconnect option when a non-weatherproof, indoor-rated switch is required.
