The DIHOOL Miniature Circuit Breaker does exactly what it's supposed to. It’s reliable, easy to install, and provides solid protection for my electrical setup. There’s not much more to say—it works perfectly and meets all expectations. If you need a dependable MCB, this one gets the job done!

### ⭐⭐⭐⭐⭐ Does the job well
*by D***. on 19 July 2023*

Ordered as circuit breaker/isolator to sit between 2 160W solar panels and Epever solar controller on my narrowboat solar setup. Good design with track supplied so easy to install. Easy access terminal slots so no issues with cables and connectors supplied in separate packet. Ensure cable firmly gripped to 'spade end' connector so doesn't pop out. Easy to operate manually, have not had a 'forced' disconnect yet. Recommended.
