## Questions & Answers

**Q: How much current does the coil draw?**
A: From Mouser website: Coil Resistance: 77 Ohms, Coil Current: 125 mA

**Q: My old relay shows: coil24vac, 14fla 84lra 125vac, 8fla 48lra 277vac, and 25a, 277vac res. can i use this to replace mine?**
A: No, the amperage ratings on this relay are lower than the one you are trying to replace.
The 90-380 relay has these specs:
12 Amps. Continuous, 60 Amps. Inrush @ 125 VAC
  8 Amps. Continuous, 48 Amps. Inrush @ 250 VAC
18 Amps. Continuous @ 277 VAC
FLA is Full Load Amps, "Continuous"
LRA is Locked Rotor Amps

**Q: I only have 4 wires on my ac unit will this relay still work?**
A: Really can't answer that without more details.
If your four wires are two for the coil and two for the fan, then yes but...
terminals 1&3 are the coil
terminals 2&4 are the N.O.
terminals 5&6 are the N.C.

**Q: With the leads to the coil energized with 24v the relay just buzzes; no switching happens. Does this mean I received a defective relay?**
A: If you connect the 24VDC version in a system that needs a 24VAC relay, the AC will cause the DC coil to buzz and will fail to function. Make sure you get the 24VAC version in a system that uses AC on the coil side.

This switching relay works well with Wi-Fi thermostat

### ⭐⭐⭐⭐⭐ 







  
  
    As advertised. Works.
  

*by K***C on Reviewed in Canada on 11 June 2020*

No issues. Simple replacement or use to augment your HVAC system. This is a quality part, not a cheap knockoff. You don't want to risk anything effing up your HVAC controls because they will fail at the worst possible time, guaranteed.

### ⭐⭐⭐⭐⭐ 







  
  
    Coil only draws 320ma. Works great for using furnace to switch on humidifier
  

*by S***N on Reviewed in Canada on 20 February 2021*

Works great. I measured the current draw of the coil it is only 320ma. Was worried because using my new furnace to control a humidifier and didn't want to much load. But 320ma is very low. I am turning on a small fan and solenoid of the humidifier with the contacts. Works great and my home is no longer dry.
