## Questions & Answers

**Q: How do I know if this is the right contactor for my equipment?**
A: If your old contactor has a 240V Coil and is rated 40A, 30A, or 25A. This 40A model is a heavy-duty upgrade for lower amp units. Rule: Coil voltage must be exact; Amps can be higher, but never lower than your original one.

**Q: Can I use this on irrigation systems, deep well pumps, Industrial curing ovens, sauna heaters, gymnasium lighting?**
A: It's designed for these "Line Voltage Control" applications. Because it features a 208/240V Coil, it matches the high-voltage power source used by this equipment, eliminating the need for a step-down transformer. Make sure coil voltage match.

**Q: Does this contactor support Auxiliary Contacts?**
A: Yes. This model features standard mounting points on the side for adding auxiliary contact blocks (Snap-on type), check our SUNLEE Auxiliary switch.

**Q: I have a 24V thermostat. Will this work for my AC?**
A: This contactor has a 240V Coil. Most residential thermostats output a 24V signal. If you connect a 24V thermostat to this 240V coil, it will not engage. Please purchase our model with a "24V Coil" for standard HVAC applications.

**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
