OEM Carrier 3-Pole Contactor 40A 208/240V for Model 06E07EB027940

This OEM Carrier contactor (part #HN53CD208) is the factory-specified high-voltage switching relay for the Carrier 06E07EB027940 commercial compressor unit. The contactor acts as the muscle behind your thermostat's 24V signal — when energized, it closes the high-voltage circuit to the compressor and associated loads. A failed contactor means the compressor won't start, runs continuously without shutting off, or causes nuisance tripping. Burned or pitted contacts are the most common failure mode on 3-pole units due to high locked-rotor amperage at startup.

• Specs: 3-Pole, Single-Throw | 40A FLA / 160–240A LRA | Coil Voltage: 208–220V/50Hz & 208–240V/60Hz | VAC Rating: 240–600V | Overload & push-to-trip protection | 4-hole mount
• OEM vs Generic: OEM contactors use factory-matched silver-alloy contact tips rated to exact LRA tolerances for this compressor. Generic contactors often use lower-grade alloys that pit and weld faster under heavy 3-phase loads, risking compressor damage.
• Install difficulty: 3/5 — Requires lockout/tagout of all power before servicing. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (verify coil resistance ~20–30Ω before install), and a camera or phone to photograph wiring layout prior to disconnection. Always confirm coil voltage matches your control circuit.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: This contactor is the direct OEM replacement for Carrier model 06E07EB027940. Verify your existing contactor's pole count, FLA rating, and coil voltage on the data plate before ordering.
