It features a 24 volt AC coil and a 2-pole configuration rated at 40 amps. Definite purpose contactors like this one are purpose-built for specific load types, making them a standard component in compressor and condenser fan motor circuits. Licensed HVAC technicians install and replace these contactors during routine maintenance and equipment repair on residential and light commercial systems.\u003c\/p\u003e\u003cp\u003eThis contactor is suited for residential and light commercial HVAC applications where a 24 VAC control signal switches high-voltage compressor or fan motor circuits. Typical install scenarios include replacement of failed or pitted contactors in split-system condensing units, heat pumps, and packaged rooftop units. The 2-pole design is the most common configuration found in single-phase compressor circuits, and the 40-amp rating accommodates a wide range of residential compressor loads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e24 VAC coil voltage for direct interface with standard low-voltage thermostat control circuits\u003c\/li\u003e\n\u003cli\u003e40-amp contact rating suitable for single-phase compressor and motor loads\u003c\/li\u003e\n\u003cli\u003e2-pole configuration covers both line legs in single-phase applications\u003c\/li\u003e\n\u003cli\u003eDefinite purpose design built for HVAC and refrigeration duty cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement definite purpose contactor for residential and light commercial HVAC condensing units and packaged systems requiring a 2-pole, 40-amp, 24 VAC coil contactor.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eContactor replacement is performed by a licensed HVAC technician. Disconnect and lock out all power to the unit at the disconnect box before removing the existing contactor. Note all existing wire terminations before removal and verify the replacement contactor matches the coil voltage, pole count, and amperage rating of the original. Installed contactors should be inspected for proper seating and secure terminal connections before restoring power.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoil Voltage\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Rating\u003c\/strong\u003e: 40 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Poles\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContactor Type\u003c\/strong\u003e: Definite Purpose\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MARS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: mars-17425\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MARS","offers":[{"title":"Default Title","offer_id":51138371289394,"sku":"MARS-17425","price":29.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305532176.png?v=1778254529","url":"https:\/\/voomisupply.com\/products\/mars-mars-17425-definite-purpose-contactor-40a-24v-2-pole","provider":"Voomi Supply","version":"1.0","type":"link"}
