This 1-pole component is the primary electrical switch for your air conditioner's compressor and condenser fan motor, designed to engage when the 24V thermostat signal is received. As a \"1-pole with shunt\" design, it maintains a continuous \"hot\" leg to specific components, such as a crankcase heater or transformer, while switching the primary power leg to start and stop the cooling cycle.\u003c\/p\u003e\n\u003cp\u003eDesigned for universal field replacement, the TP-CON-1\/24\/40 features a 40-amp rating, making it a robust upgrade or direct replacement for standard 30-amp or 40-amp units.

If the original had a shunt, the TP-CON-1\/24\/40 is your direct match. Ensure the \"always hot\" wire is connected to the shunted side; this keeps your compressor's crankcase heater active during the off-cycle to prevent liquid refrigerant from \"slugging\" the compressor on startup.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eTP-CON-1\/24\/40\u003c\/strong\u003e is a direct replacement for many OEM and aftermarket 1-pole contactors including:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e Trane CTR02574, CTR2574, Rheem 42-42478, 42-20619-01, Siemens 45GG10AJA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAftermarket Cross-Refs:\u003c\/strong\u003e Fasco H140, Honeywell DP1040A5004, Packard C140A, C140, MARS, JARD\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCondensing Units:\u003c\/strong\u003e Compatible with most 1.5 to 5-ton residential AC and Heat Pump units from Trane, American Standard, Carrier, Bryant, and Goodman.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRefrigeration:\u003c\/strong\u003e Suitable for commercial walk-in coolers and refrigeration racks requiring 24V control.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRADEPRO®","offers":[{"title":"Default Title","offer_id":52451518021995,"sku":"817506020124","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/Contactor1-24-40.jpg?v=1774387022","url":"https:\/\/tophvacparts.com\/products\/tradepro-tp-con-1-24-40-1-pole-contactor-with-shunt-24-vac-40-amp","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
