OEM Carrier 2-Pole Contactor 30 Amp 24V Coil for Model PY3PPA042060NB (HN52KC025)

This OEM-specification 2-pole contactor is the factory-matched replacement for the Carrier PY3PPA042060NB split-system air conditioner. The contactor is the high-voltage switching relay that receives a 24V signal from your thermostat and closes the circuit to power the compressor and condenser fan motor. When the contactor fails — due to burned or pitted contacts, a welded/stuck plunger, or a failed coil — your system will either refuse to start entirely, run continuously without shutting off, or trip the breaker repeatedly.

• Specs: 2-Pole (Double Pole) | 30 Amp RES rating | 24VAC coil voltage | 50/60 Hz | Compatible with 208–240V supply circuits | Replaces OEM part number HN52KC025 (current successor: HN52KC024)
• OEM vs Generic: OEM contactors use silver-alloy contact tips rated to factory arc-interruption specs. Generic contactors often use lower-grade contact material that pits faster under load cycling, shortening service life significantly in high-run-time climates.
• Install Difficulty: 2/5 — Shut off power at the disconnect and breaker before opening the unit. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter. Photograph all wiring before disconnecting terminals. Swap wires one at a time to avoid miswiring the load side.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY3PPA042060NB packaged unit. This contactor is also widely used across Carrier, Bryant, and Payne split-system and packaged AC platforms with 2-pole, 30 Amp, 24V coil contactor specifications. Always verify your existing contactor's pole count, amp rating, and coil voltage against your unit's wiring diagram before ordering. Questions about fitment?
