{"product_id":"762-075","title":"762-075","description":"This 3\/4\" auto-reset disc limit switch is a critical safety component designed for high-heat appliance applications, particularly in residential furnaces and HVAC systems. Functioning as a high-limit control, this switch monitors internal temperatures to protect your equipment from overheating. When the ambient temperature reaches the fixed trip point of 140°F, the snap-action thermal disc opens the circuit to shut down the heating source. As the system cools by 40°F, the switch automatically resets to restore operation. This durable, precision-engineered thermal switch is an essential replacement part for maintaining safe operating temperatures and ensuring the longevity of your heating equipment.\u003cbr\u003e\nType: High Limit Control Switch\u003cbr\u003e\nSize: 3\/4 inch disc\u003cbr\u003e\nApplication: Commonly used in forced-air furnaces, heat pumps, and HVAC blower assemblies to prevent over-temperature conditions.\u003cbr\u003e\nSpecifications: Open Temperature: 140°F; Reset Differential: 40°F; Reset Type: Automatic; Configuration: Normally Closed (NC); Mount Type: Surface Mount Flush Disc","brand":"BCFurnace","offers":[{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 762-075","offer_id":47251515146525,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 025-41320-000","offer_id":47251515244829,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ 02541320000","offer_id":47251515277597,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ S1-025-41320-000","offer_id":47251515212061,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true},{"title":"3\/4\" DISC LIMIT SWITCH AUTO RESET L140-40F \/ S1-02541320000","offer_id":47251515179293,"sku":null,"price":52.5,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/8af84431c91642c999d4f08593e1f627.webp?v=1773958862","url":"https:\/\/bcfurnace.myshopify.com\/products\/762-075","provider":"BCFurnace","version":"1.0","type":"link"}
