LANGIRLANGIR DC 40A Circuit Breaker, 1 Pole DIN Rail Mount, 250V Solar PV Disconnect Switch, Overcurrent Protection for Battery, Home, RV, and Industrial Electrical Systems

These breakers seem to be well made and are about half to a third the price of other name brand din rail mounted breakers. Thumbs up.

Worked as advertized

I bought several of these to make a DIY solar combiner box, they seem to OK, only time will tell. The DIN rail mounting is nice.

Nice solid circuit breaker for my solar system. The connection clamps are really well made. Accepts larger wire no problem. The on/off had me confused though. I "thought" the red showing when in the UP position would mean "off" and the green when down would be "on". The little line and circle meant nothing to me and it would be nice to have the words "ON" and "OFF" printed on the breaker somewhere. Of course, it was the opposite. The green was "off" and the red "on" so flipped UP is ON and flipped down is OFF. It has a good solid click and the breaker is solid and put together well. Reasonably priced and shipped promptly.

Good quality product
