It controls small electrically driven air compressors by monitoring system pressure and interrupting the motor circuit when the set pressure is reached. The switch includes an integrated 2-way pressure release valve that unloads the compressor head on shutdown, allowing easier restarts. This switch is installed by electricians or HVAC-R technicians servicing small compressor-driven equipment in light commercial or residential shop environments.\u003c\/p\u003e\u003cp\u003eThe FHG12J52XCP is designed for use on small electrically driven air compressors in residential, light commercial, and shop settings. It is well suited for portable and stationary compressors where reliable pressure cut-out control is needed. The 1\/4 inch NPT female inlet port connects directly to standard compressor manifold or tank fittings. The integrated pressure release valve vents line pressure between the pump and the switch at shutdown, reducing motor load on restart and extending compressor service life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCuts off at 125 psi for consistent pressure control on small air compressors\u003c\/li\u003e\n\u003cli\u003eIntegrated 2-way pressure release valve unloads pump head on shutdown for easier motor restart\u003c\/li\u003e\n\u003cli\u003e1\/4 inch NPT female connection fits standard compressor tank and manifold ports\u003c\/li\u003e\n\u003cli\u003ePumptrol design built for electrically driven compressor motor control circuits\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited to portable and stationary small compressor installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pressure switch for small electrically driven air compressors using a 1\/4 inch NPT female inlet connection and requiring a 125 psi cut-out set point.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed electrician following applicable NEC requirements for motor control circuits. De-energize the compressor and bleed all tank pressure to zero before removing or installing any pressure switch. Ensure the NPT threads are sealed with appropriate thread sealant rated for compressed air service. Do not exceed the rated pressure of the switch or install it on systems requiring a cut-out set point other than what the switch is rated for.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut-Out Pressure\u003c\/strong\u003e: 125 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Connection\u003c\/strong\u003e: 1\/4 inch NPT Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Release Valve\u003c\/strong\u003e: 2-Way integrated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.65 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5 per package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FHG12J52XCP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51524995940658,"sku":"FHG12J52XCP","price":220.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a588ae755e9e499f07c9d7e892518f3f_b25f9ab3-f320-4442-81b8-3de812f32373.jpg?v=1785462580","url":"https:\/\/voomisupply.com\/products\/square-d-fhg12j52xcp-compressor-pressure-switch-125-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
