Factory Authorized Parts™ HN61PC003 Heavy Duty Power Relay 24V DPST T92S7D22-22-01

The High-Power Switching Core

The HN61PC003 is a high-capacity, industrial-grade power relay designed to act as the primary switching interface for Carrier, Bryant, and Payne air handlers and heat pumps. As a genuine Factory Authorized Part, this component serves as the "handshake" between low-voltage control signals and high-amperage hardware. It is specifically engineered to handle the heavy electrical inrush associated with blower motors and electric heat strips, providing reliable isolation between the sensitive 24V furnace control board and the high-voltage (120V-277V) power supply. By utilizing a Double-Pole Single-Throw (DPST) configuration, it ensures complete circuit disconnection for enhanced system safety and efficiency. 

Key Features:

• Genuine OEM Precision: Engineered as part number HN61PC003 to meet the exact coil resistance and contact material standards required by Carrier Corporation.
• Heavy-Duty 30A Rating: Robust power handling capable of switching high-wattage electric heating elements and high-horsepower blower motors without contact welding.
• Double-Pole Isolation: The DPST design allows for the simultaneous interruption of two power legs, providing a higher level of safety than standard single-pole relays.
• Noise-Reduced Operation: Features a high-quality electromagnetic coil designed to eliminate the "chatter" and hum often associated with aging universal relays.
• Vibration-Resistant Housing: Encased in a durable, heat-resistant shell that protects the internal contacts from the constant vibration of air handler cabinets.

🛠️ HVAC Depot Pro Tip: Practical Installation Advice

"Take a Picture First!" Before pulling the wires off the old relay, photograph the terminal numbering. The HN61PC003 uses a specific terminal layout (1-2-3-4-6-8) where the coil pins and the load pins are positioned in a non-linear fashion. Miswiring the 24V coil to a high-voltage load pin will immediately destroy your furnace control board. Once installed, perform a "Continuity Check" across the load terminals (with power off) while manually depressing the relay armature to ensure the contacts are seating properly before restoring power.
