{"product_id":"021-898","title":"021-898","description":"This premium thermal limit switch is a critical safety component designed for HVAC and heating systems. Acting as a high-limit control, this fan disc switch monitors internal temperatures to provide essential overheating protection. When the system reachers the critical threshold of 195°F, the bimetallic disc snaps to open the circuit, cutting power to prevent equipment damage and ensure safe operation. Ideal for residential or commercial air handlers and furnaces, this switch is a common replacement part for units experiencing frequent cycling or safety shutdowns. Its durable construction ensures a long service life and reliable temperature regulation in demanding heating applications.\u003cbr\u003e\nType: Fan Disc High Limit Control Switch\u003cbr\u003e\nSize: Standard Fan Disc\u003cbr\u003e\nApplication: Commonly used in HVAC systems, forced-air furnaces, and commercial air handling units to monitor heat exchanger temperatures and provide thermal safety protection.\u003cbr\u003e\nSpecifications: Opening Temperature: 195°F; Switch Type: High-Limit Thermal Cutout; Reset Type: Automatic; Configuration: Normally Closed (NC) under standard operating temperatures.","brand":"BCFurnace","offers":[{"title":"SWITCH; THERMAL LIMIT, HI-LIMIT, 195F OP \/ 021-898","offer_id":50216345305373,"sku":null,"price":435.59,"currency_code":"CAD","in_stock":true},{"title":"SWITCH; THERMAL LIMIT, HI-LIMIT, 195F OP \/ SWT04706","offer_id":50216345338141,"sku":null,"price":435.59,"currency_code":"CAD","in_stock":true}],"url":"https:\/\/bcfurnace.myshopify.com\/products\/021-898","provider":"BCFurnace","version":"1.0","type":"link"}
