Designed specifically for air conditioning and heat pump units, this critical safety component monitors refrigerant levels to provide high-limit protection for the compressor. By automatically interrupting the electrical circuit when internal pressure reaches 450 PSI and resetting at 300 PSI, it prevents catastrophic system failure and equipment damage. This air-proving pressure sensor is a vital replacement part for maintaining efficient climate control and reliable operation in both residential and commercial cooling systems.\u003cbr\u003e\nType: Air Pressure Switch \/ High Pressure Cutout\u003cbr\u003e\nSize: Compact\u003cbr\u003e\nApplication: Used as a safety limit switch in air conditioning systems and heat pumps to monitor refrigerant pressure and protect the compressor from over-pressurization.\u003cbr\u003e\nSpecifications: Cutout Pressure: 450 PSI; Reset Pressure: 300 PSI; Function: High-pressure safety cutout; Compatibility: Air conditioning and heat pump systems.","brand":"BCFurnace","offers":[{"title":"LENNOX SWITCH, HIGH PRESSURE, 450\/300 \/ 000-656","offer_id":50215868989725,"sku":null,"price":68.65,"currency_code":"CAD","in_stock":true},{"title":"LENNOX SWITCH, HIGH PRESSURE, 450\/300 \/ 102447-01","offer_id":50497950646557,"sku":null,"price":68.65,"currency_code":"CAD","in_stock":true},{"title":"LENNOX SWITCH, HIGH PRESSURE, 450\/300 \/ 65W67","offer_id":50215869022493,"sku":null,"price":68.65,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0836\/7298\/9981\/files\/58f3f5f415514480a69a019416122a80.webp?v=1773961115","url":"https:\/\/bcfurnace.myshopify.com\/products\/000-656","provider":"BCFurnace","version":"1.0","type":"link"}
