The Square D VH363GL Heavy-Duty Safety Switch is engineered for demanding industrial and commercial power distribution applications where reliable, code-compliant motor and feeder isolation is critical. Rated at 100 A and 600 V AC/DC with a 3-pole fusible configuration, this switch handles motors up to 100 hp at 600 V DC and 60 hp at 480 V AC — making it a go-to choice for industrial machinery, HVAC systems, compressors, and heavy process equipment. The NEMA 1 steel enclosure suits indoor installations, while the surface-mount design simplifies placement in mechanical rooms, switchgear lineups, and equipment panels. Compatible with H, K, R, and J fuse types, and rated up to 200 kA short-circuit current with R & J fuse rejection clips, the VH363GL delivers the protection margin that inspectors and project engineers expect. UL Listed (File E2875) and RoHS compliant, it meets the standards required on Canadian and North American job sites.
