When reliability and quick, controlled isolation matter, the Westinghouse HFN364 provides a clear, practical advantage over non-fused or less robust disconnects.\u003c\/p\u003e \u003ch3\u003eHow it works in practice\u003c\/h3\u003e\n\u003cp\u003eIn everyday use, this fused safety switch sits at the main service disconnect or at point-of-use where equipment needs to be isolated for servicing. Fusing ensures overcurrent protection while the three-pole design ensures all phases can be safely opened, reducing the risk of arc flash and accidental energization during maintenance. Its compatibility with lockout\/tagout procedures means teams can confidently padlock the switch in the OFF position while work is performed.\u003c\/p\u003e \u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage rating:\u003c\/strong\u003e 200A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eNumber of poles:\u003c\/strong\u003e 3-Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Fused Safety Switch\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Westinghouse\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e HFN364\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Amp-State","offers":[{"title":"Default Title","offer_id":46383677178018,"sku":"HFN364","price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/disconnect_switches_generic_37354c21-0f03-4cf6-b587-9ca87704bd70.png?v=1765252066","url":"https:\/\/www.ampstate.com\/products\/westinghouse-hfn364-disconnect-switch","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
