Questions & Answers

I'm looking for an original equipment manufacturer (OEM) replacement for a hlr3800-based system. 4af3l is a type of motor starter relay with a potential of 4af3l. Is this something you can do?

This is a two-pole, single-throw switch, not a three-pole, double-throw switch. It's a potential relay that you're looking for.

What is the maximum amount of current it can handle?

The amperage at which the load is loaded is unknown. Keep in mind that it's only a slave relay, so the only load it'll be carrying is the coil from your larger relay.

Is there a latching mechanism in place to prevent rapid cycling when grid voltage 'flickers'? What is the distinction between cut-and-paste and cut-and-paste? in addition to cutting- voltage that is not present ?

During these flickers, a capacitor in the coil circuit, as I recall, acts as a shock absorber. The cut in voltage is the amount of voltage required to actually energize the coil, which may be greater than the cut out value.

Is it possible to use this to turn on a 120-volt inline duct fan that is supposed to be controlled by a 24-volt thermostat?

You should be able to find Supco's website as well as a PDF of the specifications by searching for Supco 90340. According to the PDF, the coil voltage is 24 volts and the model number is 90340. Honeywell R8222D1014 is the next step. However, because that is what I use the relay for, I would say yes.

This is a waste of time
3/5

After failing to get it to work properly after wiring a small panel with it, I became enraged and tore the relay apart; it's a double pole SINGLE THROW, not a DOUBLE THROW. I'm not going to buy anything else from Supco. To take its place, I ordered an Omron. I've had no problems with Omron in the past, and I'm hoping that won't be the case this time. I ordered this one because it was the first one I saw and I was in a hurry. What a waste of time. Now I just have to wait a few days for another one to arrive.

Delivery was very quick
4/5

The picture is incorrectly positioned. When my AC fan relay failed, I ordered a replacement that I thought was the same as the original. I got one with ten pins instead of the eight shown in the picture. Even so, the relay was operational. I taped the two extra pins together to prevent future shorts. I got the relay in one day, which was nice and sufficient.

Insurance at a low cost It is never convenient to keep one on hand for my air conditioner when the relay fails
5/5

It's simple and inexpensive to change, and it's better to be prepared than to be caught off guard.

Great product at a great price; it's ideal for wiring lights and fountains, which is exactly what I needed it for
5/5

It's very simple to install because you can use standard size crimp on spade connectors to connect the wires. I initially misread the schematic, but it was quickly corrected. This heavy-duty relay and contacts are capable of handling a significant load.

This isn't going to work
3/5

It's pointless. This isn't going to work. I tried several times to energize the coil, but the circuit between the contacts would not complete. I'll be returning for a refund.
