{"product_id":"020-928","title":"020-928","description":"This high-performance L155F High Limit Switch is a critical safety component designed for HVAC systems, furnaces, and air handlers. As a normally closed (NC), single-pole single-throw (SPST) fan disc switch, it acts as a thermal safeguard by monitoring internal equipment temperatures. When the temperature reaches the 155°F threshold, the switch automatically opens to break the electrical circuit, preventing the appliance from overheating and protecting internal components from damage. Featuring an auto-reset function, the switch restores connectivity once the temperature drops to a safe level, ensuring continuous and reliable operation. This durable thermal control is essential for maintaining the safety and efficiency of residential and commercial heating units.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: Standard Fan Disc\u003cbr\u003e\nApplication: Commonly used as a safety cutout in forced-air furnaces, electric heaters, and HVAC air handling units to prevent system overheating.\u003cbr\u003e\nSpecifications: Temperature Rating: L155F (Opens at 155°F); Circuitry: Single Pole Single Throw (SPST); Contact State: Normally Closed (NC); Reset Type: Automatic","brand":"BCFurnace","offers":[{"title":"Limit Switch, L155F, Auto Reset, Normally Closed, SPST \/ 020-928","offer_id":50216207155485,"sku":null,"price":218.96,"currency_code":"CAD","in_stock":true},{"title":"Limit Switch, L155F, Auto Reset, Normally Closed, SPST \/ CNT04820","offer_id":50216207188253,"sku":null,"price":218.96,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/6b4163f6a71e4b12a2438e596f2b774c.webp?v=1773962737","url":"https:\/\/bcfurnace.myshopify.com\/products\/020-928","provider":"BCFurnace","version":"1.0","type":"link"}
