OEM Carrier 2-Pole Contactor 30 Amp 24V Coil HN52KC025 for Model PY2PPB030040NB

This OEM Carrier contactor is the factory-specified replacement for the Carrier PY2PPB030040NB condenser unit. The contactor is a high-voltage switching relay controlled by the thermostat's low-voltage (24V) signal — when the thermostat calls for cooling, the 24V coil energizes and closes the contacts, sending 240V power to the compressor and condenser fan motor. When the contactor fails, symptoms include an AC system that simply won't turn on, buzzing or chattering at the outdoor unit, or a system that trips the breaker due to welded/pitted contacts drawing excessive current.

  • Specs: 2-Pole (Double Pole) | 30 Amp FLA / 20 Amp RES | 24VAC Coil Voltage | 600V rated | Tyco Electronics 3100A20Q328 | Factory-matched replacement for OEM part# HN52KC025 (superseded by HN52KC024)
  • OEM vs Generic: OEM contactors are manufactured to exact Carrier factory specifications, with precision-grade silver alloy contacts that resist pitting and welding under load. Generic contactors may use lower-grade contact materials, increasing the risk of premature failure and compressor damage.
  • Install Difficulty: 2/5 — Always shut off power at the disconnect box and the breaker before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, a multimeter to verify coil voltage, and electrical tape. Photograph all wire connections before removing the old contactor to ensure correct reinstallation.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PPB030040NB condenser unit. Also fits a wide range of Carrier, Bryant, and Payne equipment using a 2-pole, 30-amp, 24V coil contactor. Always verify specs on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy — ships today!

How do I replace the contactor on my Carrier OEM Carrier 2-Pole Contactor 30A 24V HN52KC025 — PY2PPB030040NB?
Difficulty: Medium (30–45 min)

My AC clicks but the compressor won’t turn on. What’s wrong?
Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
Is this contactor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier contactor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
