Use it to provide disciplined, code-resilient power disconnects for maintenance, service outages, or process line isolation in warehouses, manufacturing plants, distribution centers, and large-scale commercial buildings. Its fused design helps protect downstream equipment and helps maintain system integrity when switching under load.\u003c\/p\u003e \u003ch3\u003eHow this compares to non-fused disconnects\u003c\/h3\u003e\n\u003cp\u003eFused safety switches like the HU364 offer an added layer of protection by interrupting fault currents directly within the switch assembly. This can improve fault handling, reduce arc exposure, and contribute to more predictable startup and shutdown behavior compared with non-fused disconnects—especially in environments with high inrush or fault-prone circuits.\u003c\/p\u003e \u003ch3\u003ePractical tips for installation and use\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eInstall in accordance with all applicable electrical codes and the manufacturer guidelines to ensure optimal safety and performance.\u003c\/li\u003e \u003cli\u003eBefore service work, verify isolation and implement appropriate lockout\/tagout procedures to protect personnel.\u003c\/li\u003e \u003cli\u003eKeep spare fuses on hand and replace only with the same rated components to maintain protective performance.\u003c\/li\u003e \u003cli\u003eSchedule regular inspection of the enclosure and connections to sustain long-term durability and reliable operation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Amp-State","offers":[{"title":"Default Title","offer_id":46383608430754,"sku":"HU364","price":1010.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/disconnect_switches_generic_3afca8b9-014b-4df7-b4b2-38b88abb2e99.png?v=1765250954","url":"https:\/\/www.ampstate.com\/products\/square-d-hu364-disconnect-switch-4","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
