Satisfying

Satisfactory and affordable, this product isn't fully protected at the connections. You'll need to cover them with a good quality silicone sealant specifically designed for electrical connections to protect them.

However, I recommended this circuit breaker because of its attractive price.

Good first impression, but no function

The switch appears to be well-made and well-assembled. Whether an M6 bolt is suitable for a 250A circuit breaker is debatable. Unfortunately, the 250A breaker trips after only a short time at around 125A. Therefore, it is not functioning correctly.

Cheap price, poor quality

I bought several of these to replace all my ANL fuses, and Ive just had too many issues to give more than 2 stars. It seems that the manufacturing and operating tolerances are all over the place! One 80A breaker was faulty already at delivery and wouldnt trip when tested. That was replaced quickly and free of charge so no big issue. Now I have two other 80A circuit breakers tripping all the time at constant 50A (dcdc charger) and 60A (shore power) even at normal room temperatures. Basically, cant recharge my house batteries until I get these replaced

Triggers too early, unfortunately not usable for me.

I bought four 60A fuses, but they're not really usable. I wanted to use them on the Orion XS 50 to replace the existing 60A fuse. The thermal cutouts trip far too early...even at 40A!
