Westinghouse WHFN261 Heavy Duty Safety Switch

The Westinghouse WHFN261 Heavy Duty Safety Switch is a 3‑phase manual disconnect and circuit isolation device for industrial and commercial electrical distribution, rated at 600 VAC or 600 VDC. Housed in a rugged wall‑mounted enclosure, it uses a manual quick‑make/quick‑break switching mechanism to deliver reliable high‑voltage switching in demanding environments. Commonly installed in motor circuits, HVAC equipment, industrial machinery, and other power distribution applications, the WHFN261 provides equipment isolation and lockout/tagout protection. The WHFN261 is designed for service entrances, feeders, and branch disconnects within industrial and commercial systems, and is compatible with industrial machinery, HVAC systems, and distribution equipment. Common replacements include Eaton DH Series, Siemens, and Schneider Electric Square D heavy duty safety switches.
