{"product_id":"762-004","title":"762-004","description":"This 5\/8-inch disc high limit switch is a vital safety component for residential and commercial heating systems. Engineered for precision heat management, this bimetal fan disc switch monitors furnace temperatures to prevent overheating. When the internal temperature reaches its high-limit threshold of 180°F, the switch automatically opens to interrupt the circuit and protect the appliance from damage. Once the system cools down by 40°F, the auto-reset feature restores the circuit, allowing for seamless operation without manual intervention. This reliable thermal cut-off is essential for maintaining furnace efficiency and ensuring the safety of forced-air heating units and HVAC equipment.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: 5\/8 inch sensing disc\u003cbr\u003e\nDimensions: 0.625 inch diameter disc\u003cbr\u003e\nApplication: Used as a safety limit control in forced-air furnaces, heat pumps, and various HVAC heating appliances to regulate temperature and provide thermal protection.\u003cbr\u003e\nSpecifications: Opening Temperature: 180°F; Closing Temperature: 140°F (40°F differential); Switch Logic: Normally Closed (NC) - Opens on Rise; Reset Type: Automatic; Sensor Type: Bimetal Disc.","brand":"BCFurnace","offers":[{"title":"5\/8\" DISC LIMIT SWITCH AUTO RESET L180-40F \/ 762-004","offer_id":47250964447517,"sku":null,"price":57.05,"currency_code":"CAD","in_stock":true},{"title":"5\/8\" DISC LIMIT SWITCH AUTO RESET L180-40F \/ HH18HA502","offer_id":47250964480285,"sku":null,"price":57.05,"currency_code":"CAD","in_stock":true},{"title":"5\/8\" DISC LIMIT SWITCH AUTO RESET L180-40F \/ L180-40F.","offer_id":47250964513053,"sku":null,"price":57.05,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/176bb7b26b9c48dd91247dbba2dd73ce.webp?v=1773960713","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-004","provider":"BCFurnace","version":"1.0","type":"link"}
