Carrier P282-0311 Contactor

The Carrier P282-0311 Contactor is a specialized 1-pole definite purpose contactor engineered for high-reliability switching in residential and light commercial HVACR systems. Rated for 30 Amps with a 24V coil, this component is a drop-in replacement for failed contactors in Carrier, Bryant, and Payne condensing units. Utilizing silver cadmium oxide contacts, the P282-0311 ensures superior conductivity and resistance to pitting or welding under inductive loads. The single-pole configuration with a shunt allows for constant power to the crankcase heater while managing the compressor and fan motor cycles. This 24 volt contactor features standard quick-connect terminals and a universal mounting base, streamlining field installation for service technicians. Built to exceed ARI 780/790 standards, it provides the mechanical longevity required for high-cycle applications. Ensure the FLA and LRA ratings match the original equipment specifications to maintain system protection and electrical integrity across the control circuit.

Key Benefits for Contractors

• OEM Compatibility: Precision-engineered for seamless integration with Carrier P282-0311 specifications.
• Enhanced Durability: High-grade 30 Amp contacts minimize electrical arcing and extend the service life of the compressor.
• Simplified Installation: Features multi-hole mounting brackets and clear terminal labeling for fast field replacement.
• Reliable Switching: The low-VA coil ensures consistent engagement even during voltage fluctuations in the 24V control loop.
• Efficient Heat Dissipation: Compact frame design facilitates better airflow within the electrical control box.

Common Questions

Can I use a 2-pole contactor to replace this 1-pole model?
While a 2-pole contactor can physically break both legs of power, the Carrier P282-0311 is a 1-pole unit with a shunt designed to keep one leg hot. Replacing it with a 2-pole unit may require wiring adjustments for crankcase heaters.

What causes this contactor to chatter or hum?
Chattering is usually indicative of low voltage at the 24V coil, often caused by a failing transformer, a restricted thermostat wire, or a high-pressure switch cutout. Ensure a solid 24V signal is reaching the coil.

Is this contactor rated for both resistive and inductive loads?
Yes, while typically used for 30 Amp inductive loads (motor loads), it also carries ratings for resistive loads (heating elements) found in specific HVAC applications.
