Compact & Awesome!
Absolute smallest disconnect ever handled & perfect for my undercounter commercial dishwasher limited space. Bright red handle great design to see up or down from a distance. Only suggestion is to make lid bit removable friendly so can access line lugs at top & if mount top hole had slot to hang for ease of mounting like industry practice. Overall awesome design & prompt delivery as promised though about an hour later than window promised. Installed & functions as designed without an hitch.

Missing critical screws
It was missing one of the 6 screws that clamp down on the wire. Annoying!Otherwise a good product that is small and doesn't take up much space.

Too small
Great product. Great price. Returned because the box wouldn't receive 1 1/4" conduit.

Terrible quality, broke just after installed
I ordered this several months ago as a switch for my large air compressor. I didn’t install it until last week. As I was installing it the plastic handle used to switch it on and off broke making it very hard/dangerous to use. Because I kept it well over the 30 day return period before I installed it I suppose I’m stuck with it. I learn by my mistakes, so use stuff you order before the return period ends. Very poorly made product for just under $40.00.

Missing parts and no ground bar . . . .
Per many other reviews, my first unit received was missing two wire lug screws . . . Also not noted in the product description is the fact you need to order a ground lug kit at additional cost as Siemens apparently believes making your installation safe and code compliant should cost extra money.This definitely a light duty switch. It is also a much smaller form factor than one would anticipate.One should also be aware this is a 3 wire cutoff. A 2 wire version is available at much lower cost from other sources.

Space is tight
Used this with 8 AWG wire and it was definitely tight in there. There's only a single knockout on the bottom and one on the left side, so you're limited in how you're going to get your wires in and out.
