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

If your looking for a Three Phase Switch to use this is a great option. Small and easily installed. Used to power a Paint Powder Booth. Very economical as compared to other options.

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.

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.

I used this to wire up a three-phase 220V shop tool. If you need a 30-amp tri-pole switch for not a lot of money, this one has your back. Fits in a regular wall box. Makes a satisfying thud sound when toggled.

Installed in a snap!

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

I bought these as replacements for cheap two pole switches that I found were used on my 230v, 2-2.5 HP 1 phase pool motors. I like to make sure there is complete disconnect and the grounds aren't substituted for the neutrals. They are expensive and required a little tab mods to fit in my mounting boxes, but they work flawlessly and I have the satisfaction that Hot-neutral-Hot are completely disconnected when I flip the switch and case grounds are isolated. I rewired the motors to green case ground and switch to neutral center-tap.

Exactly what is in picture and description. And cheap!! I plan to order a few more to have on hand. Almost half the price of local electrical supply houses. Great buy
