Super happy!
Really heavy duty product. Super happy I got this one and not the mini. Really like this one if you have the space for it. Built like a tank.

I run 200 amps through it and no heat up
I upgraded my solar array and while working on it found out there was intense heat coming from somewhere (only 80 amps out of 200). Turns out the switch I had that was rated the same as this one was not actually very good. This one is a lot bigger and easier to get the 0/4 cable connected. I now run 200 amps through it and it doesn’t heat up at all.

High quality switch that is ignition protected and IP66 waterproof ...
High quality switch that is ignition protected and IP66 waterproof rated. The connection studs are tin plated and long enough for each to hold multiple cable lugs. One side of the "single circuit" switch version (3000) has two lugs in common so there is even more room for cable connections. The 600A continuous, 900A (5 min) and 1750A (30 sec) ratings are adequate to handle heavy duty applications on boats and motorhomes. Note that the cable lug studs are for 1/2" diameter lugs, so if you are relocating cables from some other source you may need to drill out or replace your cable lugs. I have installed several of these and have never had a problem or failure.

Super heavy duty
This switch is super heavy duty. It is good quality and works well. Used it in my RV solar install and was probably more switch then I needed which made it somewhat hard to work with for my needs.
