When system pressure drops below the set point, the switch interrupts the control circuit, preventing compressor operation under potentially damaging conditions. This type of safety control is a standard component in refrigerant circuit protection and is typically installed or replaced by licensed HVAC-R technicians during routine service or system commissioning.\u003c\/p\u003e\u003cp\u003eThe M43350 is suited for use in residential and light commercial HVAC and refrigeration applications where low-side pressure monitoring is required. It serves as a protective device within the refrigerant circuit, typically wired into the low-voltage control loop to cycle or lock out the compressor when suction pressure falls outside safe operating range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMonitors low-side refrigerant pressure to protect compressor from damage\u003c\/li\u003e\n\u003cli\u003eInterrupts control circuit on pressure drop below set point\u003c\/li\u003e\n\u003cli\u003eSuitable for refrigeration and air conditioning system applications\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement form factor for service and retrofit installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement low pressure switch for residential and light commercial refrigeration and air conditioning systems.

Recover or isolate refrigerant and de-energize the system before removing or installing any pressure switch. Follow applicable mechanical and electrical codes, including NEC requirements for low-voltage control wiring. Confirm the replacement switch set point and electrical ratings match the original equipment specifications before placing the system back in service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Low Pressure Switch\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RECTORSEAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: M43350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51306908713266,"sku":"M43350","price":43.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549473.png?v=1781302225","url":"https:\/\/voomisupply.com\/products\/rectorseal-m43350-low-pressure-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
