{"product_id":"545-150","title":"545-150","description":"The 5-inch High Limit Switch is a critical safety component designed for HVAC systems and forced-air furnaces. This thermal limit control monitors the internal temperature of the heat exchanger to protect your heating system from overheating. Engineered as a normally closed switch, it automatically opens the electrical circuit when temperatures reach the 150°F threshold, effectively shutting down the burner or heating element to prevent equipment damage or fire hazards. Featuring a 30°F differential, the switch resets once the system cools to a safe operating temperature. This high-quality replacement sensor is essential for maintaining the safety and efficiency of residential and commercial heating units.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 5-inch insertion length\u003cbr\u003e\nDimensions: 5 inches\u003cbr\u003e\nApplication: Commonly used in gas furnaces, electric air handlers, and forced-air heating systems to monitor heat exchanger temperatures and provide over-temperature protection.\u003cbr\u003e\nSpecifications: Cut-out Temperature: 150°F; Cut-in Temperature: 120°F (30°F differential); Reset Type: Automatic; Configuration: Normally Closed (NC).","brand":"BCFurnace","offers":[{"title":"5\" HIGH LIMIT SWITCH L150-30F \/ 545-150","offer_id":47251071336733,"sku":null,"price":119.02,"currency_code":"CAD","in_stock":true},{"title":"5\" HIGH LIMIT SWITCH L150-30F \/ 102857-05","offer_id":47251071402269,"sku":null,"price":119.02,"currency_code":"CAD","in_stock":true},{"title":"5\" HIGH LIMIT SWITCH L150-30F \/ 73W18","offer_id":47251071369501,"sku":null,"price":119.02,"currency_code":"CAD","in_stock":true},{"title":"5\" HIGH LIMIT SWITCH L150-30F \/ 73W1801","offer_id":47251071435037,"sku":null,"price":119.02,"currency_code":"CAD","in_stock":true},{"title":"5\" HIGH LIMIT SWITCH L150-30F \/ L150-30F","offer_id":47251071467805,"sku":null,"price":119.02,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/9dc5a72a9f1d49bfaf6a84414cf4baa5.webp?v=1773957420","url":"https:\/\/bcfurnace.myshopify.com\/products\/545-150","provider":"BCFurnace","version":"1.0","type":"link"}
