Designed for HVAC systems and industrial heating units, this auto-reset fan disc switch acts as a critical safety barrier by monitoring air temperature. The switch is engineered to trip when internal temperatures reach 150°F, effectively preventing overheating and potential system damage. Once the unit cools down by 40°F to a safe operating temperature, the automatic reset feature restores the circuit, allowing for seamless operation without manual intervention. This high-reliability component is essential for furnace maintenance, rooftop unit repairs, and air handler optimization, providing peace of mind and protecting sensitive internal components from excessive thermal stress.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: Small\u003cbr\u003e\nApplication: Commonly used in residential and commercial furnaces, rooftop HVAC units, and air handling systems to monitor temperature and provide overheat protection.\u003cbr\u003e\nSpecifications: Open Temperature: 150°F; Differential\/Close Temperature: 40°F (Closes at 110°F); Reset Type: Automatic; Configuration: Fan Disc","brand":"BCFurnace","offers":[{"title":"Limit Switch, Auto Reset, L150-40F \/ 000-774","offer_id":50215895695645,"sku":null,"price":26.87,"currency_code":"CAD","in_stock":true},{"title":"Limit Switch, Auto Reset, L150-40F \/ 59W45","offer_id":50215895728413,"sku":null,"price":26.87,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/350d2165333b4027aa236f374f13fd45.webp?v=1773961278","url":"https:\/\/bcfurnace.myshopify.com\/products\/000-774","provider":"BCFurnace","version":"1.0","type":"link"}
