The Nash CL3002 is a reliable workhorse when it’s working, but a puzzle when it fails. If you’re repairing an older unit, don’t toss the whole machine just because this relay dies. Cross-reference it, and you’ll likely find a modern replacement that drops right in.
Think of it as a for motors. When the motor draws current (i.e., it’s running), the CL3002 closes a set of dry contacts, allowing low-voltage control signals to pass. When the motor stops or fails, the relay opens—sending an alert or shutting down a system to prevent damage.
The CL3002 is a current-sensing relay (or sometimes a load controller) designed by Nash (often associated with Nash Electrical Components or rebranded for HVAC/R applications). Its job is simple but critical: monitor electrical current flowing to a load (like a compressor or fan motor) and switch a separate control circuit based on that current.
And next time you see one in the wild? Give it a nod. It’s been quietly keeping compressors safe for years.
✅ No external power needed – self-powered by the monitored current. ✅ Compact size – fits in crowded control boxes. ✅ Fixed or adjustable trip points (depending on variant). ✅ Great for retrofitting older equipment with modern safety features.
If you’ve ever peeked inside a commercial dehumidifier, air handler, or HVAC control panel, you might have spotted a small, unassuming component labeled Nash CL3002 . At first glance, it looks like just another relay or controller. But ask anyone who’s dealt with a malfunctioning unit on a 95°F day, and they’ll tell you: this little guy matters.
