This is good for nothing.
Not UL listed.
No claims for AC power or DC power, just amps and volts.
Not to be used under a load.
No claims to prevent ARCing.
I use a 600 Volt DC disconnect switch, UL listed, 3 pole, 30 amps and works under load and safe to prevent arcing.
I suggest if you want a really excellent piece of equipment that you look for Schneider, Eaton, Seimens, Square D, etc. They make these switched products both indoor and outdoor rated, with single to multiple poles, large choice of amperages and fused and unfused. They meet all codes and they pretty much last forever. There are many places online that sell for large discounts off of retail too.
