## 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 for my home air conditioner?**
A: Probably NOT. Most residential AC units use a 24V coil (low voltage). This model has a 208-240V Coil, which requires line voltage to activate. Please check the label on your old contactor carefully. If it says "24V", you need a different model.

**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: Can I use this to switch two separate 240V heating banks?**
A: Yes, absolutely. The 4-pole design is perfect for this. You can wire Heating Bank 1 to Poles 1 & 2, and Heating Bank 2 to Poles 3 & 4. Since the coil is 240V, it can be controlled directly by a 240V thermostat or sequencer without a transformer.

**Q: Is this suitable for controlling warehouse lights (Ballast/LED)?**
A: Yes. This unit is rated for Inductive and Ballast loads. The 4-pole configuration allows you to switch two separate 240V lighting circuits (breaking both L1 and L2 for each circuit) using a single 240V timer or photocell.
