Its low-voltage coil closes the high-voltage contacts to power the load and opens them to shut the unit down, a cycle it repeats countless times per season. That relentless duty wears the contacts through arcing, leading to humming, hard starts, short cycling, or a unit that fails to start. A genuine OEM C50A303011 restores dependable switching and protects your system's expensive compressor. Manufactured to Carrier's original specifications, it provides an exact match in coil voltage, amperage, and pole count for a direct fit in model C50A303011 — no rewiring or adapters needed. Installation is a quick, moderate job for a qualified technician, typically 20-30 minutes: cut power, transfer the wiring terminal by terminal, secure the new contactor, and confirm operation. Verify coil voltage compatibility first. Order before 3PM CST for same-day shipping and get your cooling system back up and running with minimal downtime.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model C50A303011.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62964830241139,"sku":"carrier-contactor-c50a303011","price":42.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-contactor-c50a303011","provider":"National HVAC Parts","version":"1.0","type":"link"}
