                    This 240V relay is very high quality and very easy to install. I used 2 of these relays in a recent installation of 3 1500W electric baseboard units. One relay can easy supply power to 2 units since the total amperage is under 16 amps the maximum current allowed under the NEC for a continuous load on a 20 amp circuit. I am a professional electrician and would highly recommend this product.

                    Comments about 240v Relay w/ Built In 24V Transformer:

                    I currently have two of these running off a single thermostat controling a total of 5 heaters on a single 30 amp circuit. The 5 heaters total 23.9 amps (just about max for the 30amp circuit)
                    The first one controls a 1000 watt baseboard and a 1500 watt
                    in wall pic a watt heater, the second controls 2 1000 watt baseboards and a 1250 watt pic a watt wall heater.
                    I needed two because my total amps exceeded the 22 the relay is rated for.

                    For install I simply split the power from a junction box to the two relays and made sure each one used the same color to the black wire on the relay (in phase) then you can simply run the R,W and optionally C from the first relay to the second and then the thermostat to the first, so on the first relay you have two wires per terminal, one from ther thermostat and one from the second relay.

                                I used this to connect my King brand ceramic baseboard heaters to my 2Gig CT100 thermostat. I tried that after failing with a couple other models because I didn't realize I needed the transformer to make this work with my baseboard heaters. Once I wired it correctly, it worked great. It makes a small click sound whenever it activates on or off (one click only), but other than that, no noise, and the click is barely dedetectable (I personally like hearing the click so I know that it is working).

                                Very simple to install.

                                                        The relay with built in transformer is a great two in one package. It worked well and met my expectations.
                                                        However, in my application with radiant ceiling heat control, my thermostat was cycling the switch too frequently. More than 6 cycles per hour. This electromechanical switch is not intended for that frequency. It emits a clicking sound when activated and deactivated. Normally this wouldn't have bothered me, but it became a little annoying simply due to the fast switching.
                                                        I ended up going with the solid state version of this product, which can handle fast cycling and operates silently.

                                                        Overall, it is a great product.

                                                                Q:

                                                                Hi
                                                                I am looking for a replacement for a Minivector 50240 which has (2) separate 20amp double pole breakers operating about 8,000 watts of baseboard from 1 24v thermostat.
                                                                Is this a possible option for me (instead of Honeywell r841E)

                                                                how many watts can this handle?
                                                                How many times can it cycle on/off per hour?

                                                                  It can handle 22 amps which is around 5250 watts, so you might need two of them to handle 8000 watts total.

                                                                  You can daisy chain two together and run both from a single 24v thermostat.

                                                                Is this a suitable replacement for the "White-Rodgers 24A01G-3", (Normally Open SPST, 240v - 72LRA, Thermostat circuit .210a @18vAC, 25A non-inductive load Thermal Relays aka, silent operators)?
