    • Works as it should
Size: 63A
I bought this as a part of my solar generator. It was very easy to set up and works well. Overall it is a good product it just feels cheaply made. The housing separated a little when I tightened the screws.

    • Super Unit to Make a Safer Solar Setup
Size: 63A
i'm using these between a set of solar panels wired in series-parallel and what has quickly become my most favorite compact Victron Solar Charge Controller, especially at its more recent favorable price (this one: https://amzn.to/3JhCLgR). I have found these miniature circuit breakers do the job perfectly: they are easy to install using the provided DIN rail and screws, easy to slide on/off or clip on/off to the rail while working with the cabling, and while a few other reviewers have mentioned cable grip, I have been fortunate, and have found the breaker to grip the cables well. It is important when purchasing breakers like these to consider size matching to ensure that the gauge of cable being used is an appropriate size for not only the electrical requirements of the system, but also for the cable slots in both the charge controller and the circuit breaker. PRO TIP: it is also important to carefully strip the wire ends to a proper length. The goal is adequate exposure to the terminals and terminal clamps, but not more than that. With both these breakers and the Victron charge controller, I was able to use 6AWG cable, stripped back about one-half inch, and the cables seated cleanly and firmly. Overall, not only is it a best-practice to safeguard your solar setup with proper breakers and/or fuses, it also makes it more convenient, safer, and provides some peace-of-mind when you need to work with it.
