Eaton DH Series Heavy-Duty Fused Safety Switch, 3-Pole, NEMA 1

The Eaton DH Series heavy-duty fused safety switch family, including the DH323FGK and DH366FGK models, delivers a rugged, enhanced visible blade single-throw disconnect for manual overcurrent protection in industrial and commercial power distribution systems. Housed in a painted steel, NEMA 1 enclosure for indoor use, these three-pole, three-wire switches are fusible without neutral and accept Class H fuses for coordinated circuit protection; ratings vary by model, with the DH323FGK rated 100A at 240V and offering maximum horsepower ratings of 7.5, 15/15, and 30/20 Hp.
