The Carrier HN61KK913 Power Duty Relay is a specialized electrical switching component engineered for high-demand HVAC applications requiring a DPDT (Double Pole Double Throw) relay configuration. Operating with a 24V coil, this relay is built to handle significant inductive and resistive loads commonly found in commercial and residential air handlers and furnaces. As a heavy-duty OEM replacement relay, it ensures direct mechanical alignment and electrical compatibility within Carrier, Bryant, and Payne equipment, maintaining the integrity of the original control circuit. This component is designed for inductive load switching, providing reliable contact closure for blower motors, compressors, and auxiliary heaters. For technicians performing HVAC relay troubleshooting, the HN61KK913 offers a rugged power duty design that mitigates contact pitting and electrical arcing, extending the service life of the control board and associated high-voltage components.

Notes

Non Cancelable / Non Returnable

• Industrial Grade Contacts: Rated for high amperage draw, ensuring reliable switching performance under heavy thermal loads.
• Versatile DPDT Configuration: Allows for simultaneous control of two separate circuits or complex interlocking logic in HVAC control systems.
• Direct OEM Fitment: Eliminates the need for field modifications, ensuring exact specifications for coil resistance and contact ratings are met.
• High Dielectric Strength: Built to withstand commercial electrical environments and fluctuations in line voltage without coil failure.

Common Questions

What are the primary indicators that a Carrier power relay needs replacement?
Technicians should look for audible humming, burnt contact odors, or a "welded" state where the relay contacts fail to open. Testing for 24V at the coil without subsequent continuity across the poles confirms a failed internal mechanism.

Can this relay replace a standard SPDT relay in an emergency?
While a DPDT relay can theoretically handle the tasks of an SPDT, the physical dimensions and terminal mapping of the HN61KK913 must align with the existing wiring harness and mounting bracket to maintain UL compliance and safety standards.

Is this relay compatible with non-Carrier equipment?
If the electrical ratings for the 24V coil and the contact amperage match the requirements of the load, this relay can be used in universal applications. However, it is specifically optimized for Carrier replacement parts protocols.
