Good Quality without the added price
Have purchased about a dozen or so of these in various ampacities. Great quality with a tested trip profile similar if not identical to more expensive brands. Solid construction. The one issue is the cheesy stud insulator that comes attached to the breaker. I end up cutting them off. They never stay in place especially if you use any dielectric grease on your contacts. Overall great, will keep buying them.

Better circuit breaker
This is the second one I've purchased, and it works perfectly. The first one installed in my camper van, this one is for my DIY house solar setup. It feels much more reliable over a cheaper circuit breaker from another manufacturer that I had to replace , which tripped at less than 40 amps after only six months of use. I should have bought this one in the first place.

Merveilleux
Parfait pour mes besoin, en réalité je me sert de ce disjoncteur dans une chaloupe pour relier ma batterie au lithium a mon moteur électrique Minn Kota, je sais bien que la plupart des gens se plogue directement de la batterie au moteur mais moi je voulais vraiment une installation sécuritaire et je ne le regrette pas du tout, très satisfait de ce disjoncteur
