OEM Carrier 3-Pole Contactor 75A 120V Coil for Model 07EB033511

This OEM contactor (part number HN53HF122) is the factory-specified replacement for the Carrier 07EB033511 commercial cooling unit. The contactor acts as the high-voltage relay that closes the main power circuit to the compressor and fan motor whenever the control circuit sends a 120V signal. When the contactor fails — due to pitted contacts, a burned coil, or contact welding — the unit may refuse to start, fail to energize after a thermostat call, or run continuously without shutting off.

• Specs: 3-pole configuration | 75A current rating | 120V AC coil voltage | 50/60 Hz | Factory-matched OEM tolerances for the Carrier 07EB033511 platform
• OEM vs Generic: OEM contactors use factory-grade silver-alloy contact tips and precision-wound coils calibrated to exact pull-in and drop-out voltages. Generic units often use inferior contact materials that pit faster under high-load cycling, shortening service life.
• Install difficulty: 3/5 — This is a line-voltage component. Always disconnect and lock out power at the disconnect box before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to confirm 0V before touching terminals), and a permanent marker to label each wire before removal. Photo all wiring connections prior to disconnecting.
• Warranty: OEM factory warranty included. Ships same business day from our warehouse when ordered before cutoff.
