Contactors like the 91421 serve as electrically operated switches that open and close the high-voltage circuit to compressors, condenser fan motors, and other high-draw loads under low-voltage control-circuit commands. The 2-pole configuration handles both legs of a single-phase load. Licensed HVAC technicians are the primary installers for this class of component.\u003c\/p\u003e\n\u003cp\u003eThe MARS 91421 is suited for residential and light-commercial cooling systems where a 40-amp, 24-volt coil contactor is specified. It is commonly installed in outdoor condensing units and packaged rooftop equipment to control compressor operation. Confirm that the amperage rating and coil voltage match the existing equipment specifications before installation. This contactor is sold as a single unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-amp load rating suitable for residential and light-commercial compressor circuits\u003c\/li\u003e\n  \u003cli\u003e24-volt coil voltage compatible with standard HVAC low-voltage control wiring\u003c\/li\u003e\n  \u003cli\u003e2-pole configuration switches both legs of a single-phase load simultaneously\u003c\/li\u003e\n  \u003cli\u003eSingle-unit sale for direct OEM-style replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement contactor for residential and light-commercial HVAC condensing units requiring a 2-pole, 40-amp, 24-volt coil contactor.

Disconnect and lock out all power to the unit before removing the existing contactor or handling any wiring. Verify coil voltage, pole count, and amperage rating match the equipment specification before installing the replacement. Do not energize the control circuit until all load-side connections are secure and covers are in place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 40 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSelling Unit\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS (MOTORS ARMATURES)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 91421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS (MOTORS \u0026 ARMATURES)","offers":[{"title":"Default Title","offer_id":68081494294834,"sku":"91421","price":39.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f90b94282563bdf3a957fa455b68fdc8.jpg?v=1793140817","url":"https:\/\/voomisupply.com\/products\/mars-91421-2-pole-contactor-40a-24v-coil","provider":"Voomi Supply","version":"1.0","type":"link"}
