Carrier HN61KK324 Relay

For contractors servicing Carrier, Bryant, or Payne equipment, the Carrier HN61KK324 Relay is the standard OEM solution for reliable circuit management. This DPST 24V Pilot Duty Relay is engineered to switch two independent circuits simultaneously using a single low-voltage signal. It is the direct replacement for part HN61KK324A, ensuring a perfect drop-in fit for residential furnaces, air handlers, and commercial 38AKS units. With a 3 Amp amperage rating and 24VAC coil, it handles pilot duty loads across heating and cooling control boards without risk of rapid wear.

The Double Pole Single Throw relay configuration is vital for isolating high-power surges from sensitive control circuits. Its robust, corrosion-resistant construction is designed for high-cycle environments, providing the HVAC electrical component longevity required in demanding industrial and residential applications. Whether you are troubleshooting a non-responsive blower motor or a primary contactor control circuit, this relay provides the precise on/off switching necessary for safe system operation.

• OEM Compatibility: Identical replacement for HN61KK324A, ensuring factory-spec performance in Carrier-family HVAC systems.
• Enhanced Circuit Isolation: Features DPST (Double Pole Single Throw) logic to manage two separate circuits with a single 24V coil signal.
• Industrial Build: Durable housing protects internal contacts from environmental threats and power fluctuations.
• Compact Footprint: Designed for easy integration into crowded control boxes and modular panels.
• Pilot Duty Efficiency: Optimized for low-voltage control, rated for pilot duty to protect thermostat circuits and control boards.

• Is the HN61KK324 interchangeable with the HN61KK324A? Yes, the HN61KK324 is the identical part and can be used interchangeably in all specified applications.
• Can this relay be used for high-voltage motor switching? This is a pilot duty relay rated for roughly 3 Amps; it is intended to control larger contactors or low-power loads, not high-amperage compressor or blower motors directly.
• How do I verify if the relay coil has failed? Using a multimeter, check for 24V at the coil terminals. If voltage is present but the DPST contacts fail to close, the internal coil or mechanism is likely compromised.
