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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wi-Fi thermostat *by M***E on Reviewed in the United States on 28 February 2024* 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. ## Frequently Bought Together - Emerson 90 380 Fan Relay 24 Volt Coil, 1 - Hotop 1 Pack 24 Volt Transformer, 40 VA AC Transformer Plug in with PTC Fuse Competible with All Versions of Ring Doorbell and Thermostat, Compatible with Nest, Ecobee, Sensi, Honeywell, 24V Adapter - 24VAC 40VA Plug in Transformer,Doorbell Transformer Compatible with All of Doorbell，Nest, Ecobee, Sensi and Honeywell Thermostat --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/310846752-emerson-90-380-fan-relay-24-volt-coil-1](https://www.desertcart.co.th/products/310846752-emerson-90-380-fan-relay-24-volt-coil-1) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
