Does what it needs to do.

The mounting clips are a little strange but once they were swung out and tightened, we were able to screw it securely to the wall. Fuse sizes are not common in the US but Amazon sells 10x38 ceramic fuses in various ratings.

Just what I needed and they had it in stock.

The combiner box is perfect for my system. Thanks



Works well enough, though the craftsmanship of the box itself is somewhat sloppy. The locking mechanism, a simple mechanical post that turns with a key. The electrical all seems sound and well installed. Functionally, the product has been perfect so far after a few months of use.
