Nash Cl3002 [updated] Online

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.

So what exactly is the CL3002? And why does it keep popping up in troubleshooting forums and repair manuals? nash cl3002

And next time you see one in the wild? Give it a nod. It’s been quietly keeping compressors safe for years. Think of it as a for motors

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. So what exactly is the CL3002

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.

❌ Not always clearly labeled – “Nash CL3002” might be obsolete or rebranded. ❌ Sensitive to harmonics or noisy loads – can false-trip. ❌ Replacement can be tricky – often discontinued, leading to cross-referencing headaches. ❌ Manuals are scarce – you’ll rely on wiring diagrams from the original equipment.

✅ 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.
