Review: Excellent replacement contactor – worked perfectly - I purchased the SUNLEE 2-Pole FLA 40 Amp, 24 VAC contactor as a replacement for a failed auxiliary heat contactor in my HVAC air handler. Installation was straightforward, and the part was an exact functional replacement. Once installed, the contactor pulled in immediately with a proper 24V call and restored full auxiliary/emergency heat operation. Build quality feels solid, terminals are well made, and the coil operates quietly and reliably. The unit handled the resistive heat load without any issues. Shipping was fast, packaging was good, and the part arrived as described. This saved me a service call and got my heat back quickly in very cold weather. I would absolutely buy this again and recommend it to anyone needing a reliable 2-pole 40A HVAC contactor. The picture below is the one I replaced, not the one being sold here.
Review: Part was delivered when promised - Works! I was able to get my well pump back up and running. Easy install

## Questions & Answers

**Q: Can this 40A contactor replace a 30A contactor?**
A: Yes. This 40A contactor is a safe upgrade for a 30A unit, provided the Coil Voltage (240V) and Poles match. Rule: Coil voltage must be exact; Amps can be higher, but never lower than your original one.

**Q: How do I choose between a 24V and 240V Coil?**
A: Check your control source. Thermostats usually use 24V. Timers or Pressure Switches (like on water heaters/pumps) usually use 240V. Always match your old part label.

**Q: Can I use this 40A contactor on my 4500W/5500W Electric Water Heater?**
A: Most water heaters (4500W/5500W) come with 30A contactors. Upgrading to this 40A model provides thicker silver contacts and better heat resistance, which can extend the lifespan of your unit and prevent contact welding.

**Q: Is this suitable for a Well Pump Control Box, Pool/Spa Heater or EV Charger**
A: Yes. It is rated for 40 Amps, making it heavy-duty enough to handle the high startup current (inrush) of pump motors. Just ensure your control switch (float switch or timer) provides a 240V signal.

**Q: My old contactor buzzes/hums — will replacing it fix that?**
A: Often yes. Buzzing can be caused by a worn coil/armature, pitted contacts, or low control voltage. Replacing the contactor commonly resolves noise if the control voltage is stable and wiring is correct

### ⭐⭐⭐⭐⭐ Protect what is important.
*by R***. on February 4, 2026*

Dust collector startup is 25Amps after installing a 30A breaker I needed a way to run the DC whenever a tool was active. Had a 15A sensor. Contactor fit the bill, a little OTT but better a little more than "Fire!"👍
