York 024-25521-KIT Contactor Kit

The York 024-25521-KIT is a high-capacity 125 amp contactor kit engineered for heavy-duty commercial HVACR applications. This 3-pole contactor is equipped with a 110v coil, providing the necessary switching power for high-tonnage chillers and industrial air handling units. As a direct replacement for 024-25521-000, this unit ensures backward compatibility with legacy York and Johnson Controls systems, eliminating the need for field modifications or bracket adjustments during a service call. In industrial environments, contactors of this scale are critical for managing heavy inductive loads; the silver-alloy contact surfaces are designed to resist pitting and welding under high-amperage draws. If you are troubleshooting a unit that fails to pull in or is showing significant voltage drops across the poles due to carbon buildup, this HVAC contactor replacement kit restores electrical circuit integrity and prevents potential motor phase loss. The robust construction and factory-spec tolerances ensure reliable power distribution to compressors and large blowers where system uptime is mandatory.
