Carrier HN52TC024 Contactor

The Carrier HN52TC024 Contactor is a factory-authorized 2-pole definite purpose contactor engineered for high-demand electrical switching in residential and commercial HVAC units. Designed as a direct OEM HVAC replacement part, this component features a 24VAC 50/60Hz coil and is rated for 32-amp inductive loads, making it the standard choice for managing compressors and condenser fans in Carrier, Bryant, and Payne systems. With a 30 FLA (Full Load Amperage) and 40 RES (Resistance Amperage) rating, it provides the robust switching capacity required to handle high-current cycles without premature contact pitting or mechanical failure. The HN52TC024 incorporates a compact footprint for easy integration into tight electrical vestibules and uses standard 1/4-inch quick-connect terminals for a secure, fast installation. When swapping out a chattering or welded contactor, utilizing this genuine Hartland Controls HCCY2XQ02AG103 equivalent ensures the circuit logic and amperage draw remain within original manufacturer specifications.

• OEM Precision: Guaranteed Carrier HN52TC024 compatibility for a seamless drop-in replacement, eliminating the need for mounting modifications or bracket adjustments.
• Heavy-Duty Switching: Rated for up to 32 amps and 150 LRA (Locked Rotor Amps) at 240V, ensuring reliable motor starting even under high head pressure.
• Durable Construction: Built to Definite Purpose Contactor standards with silver cadmium oxide contacts for extended cycle life and resistance to electrical arcing.
• Versatile Application: Ideal for heat pump contactor replacement and air conditioning condenser service, compatible with 24V control circuits and 50/60Hz frequencies.

Can I use the HN52TC024 to replace a 25-amp or 30-amp contactor?
Yes. This 32-amp rated contactor can safely replace lower amperage 2-pole contactors, providing a higher safety margin for the compressor circuit. However, always verify that the coil voltage matches your system's 24V control signal.

What are the symptoms of a failing HN52TC024 contactor?
Common signs include a loud buzzing or chattering sound from the outdoor unit, visible pitting or blackening of the contact points, or the compressor failing to engage despite receiving a 24V signal from the thermostat.

Does this contactor include a shunt?
This specific model is a 2-pole, double-pole single-throw (DPST) design, which breaks both power lines to the load for increased safety and complete circuit isolation during the "off" cycle.
