• OEM Compatibility: Matches original equipment engineering for a drop-in Carrier HN61KJ310 replacement.
• High Amperage Rating: Rated for 18-amp loads, making it suitable for high-demand fan and motor applications.
• Circuit Protection: Provides reliable electrical isolation to protect expensive control boards from surges.
• Industrial Build Quality: High-grade housing and terminal construction designed to withstand the heat and vibration of an air handler.

Is the Carrier HN61KJ310 relay compatible with other brands?
Yes, as a standard power relay within the Carrier family, it is commonly utilized in Bryant, Payne, and ICP equipment that requires an 18-amp switching capacity.

What are the symptoms of a failing power relay?
Common signs include a blower motor that fails to start despite receiving a signal from the thermostat, or a "chattering" noise indicating the contacts are not seating properly.

Can I use a lower-rated relay as a substitute?
It is not recommended. Using a relay with a lower amperage rating than the HN61KJ310 can lead to contact welding, overheating, and potential electrical failure in the furnace or air conditioner.
