Leviton MS303-DS 30 Amp 600 Volt, Three-Pole, Three Phase AC Motor Starter, Suitable as Motor Disconnect, Toggle, Industrial Grade, Non-Grounding, Black

My Mitusubishi mini-split Heat pumps I just installed have the main power (20Amp) supplied to the outdoor unit. The power and control wires and ground (4 wires total), needed a 3 pole switch to allow each indoor unit to have power cut individually (to meet code). These are the only 3-pole on/off switches I could find and seem to be good quality, but are kind of pricey. If you want to install to code these are likely your only choice. Amazon had by far the best price on them. I installed these in the wall (with normal old-work boxes) next to each unit. Worked great. Just what I needed. Used a standard switch plate. I used the 14g 4-wire cable available from eComfort where I got my mini-split units. The wire supplies power from the outdoor unit into the indoor units though the switches.

No problems with this switch. This is by far the cheapest way to turn on and off 480 Volts. There are so many restrictions for high voltage equipment and using alternative contactors and other devices are 10X more expensive.Will definitely buy this again if the need arises.

The product was delivered quickly and in excellent condition. Thank you!

All good

I needed a 3 pole switch to kill the power to 3 different circuits at the same time, this product got it done. fits your standard 4x4 electrical box with a switch cover. Easy to Install

Works as described.

Good switch

Works great, saved over $100 with this compared to going to an electrical supply store. If it lasts, it's a bargain !!
