Schneider Electric NSB H-221-N Safety Switches

Schneider Electric NSB H-221-N Safety Switches deliver heavy-duty, 30 A fusible protection in a 2-pole, 3-wire configuration built for indoor, general-purpose use (NEMA 1 enclosure). Designed for 240 VAC mains with up to 250 VDC capability, it handles about 7.5 hp at 240 VAC. The quick-make, quick-break mechanism provides fast, reliable operation, and the model can be equipped with a factory-installed neutral; it is suitable for service entrance when paired with a neutral assembly or equipment grounding kit. The H-221-N is listed as a discontinued reference as of January 31, 2024, with Schneider Electric recommending VH221N (VisiPacT) as the replacement, a heavy-duty, fused switch with a viewing window for improved position verification.
