LANGIR DC Circuit Breaker 2 Poles 1-63A 500V for Solar Energy System and Other DC System DIN Rail Installation (16A)
Description
- About this item
- JB DC Miniature Circuit Breaker isn't polarity sensitive: + and - wires can inversed without any risk. Fast trip to ensure reliable operation of the load and prolong the life of electrical circuit breakers. It can also work as on-off switch for DC load circuits.Positive and negative poles wires can inversed without any risk. More precise trips based on current, even in extreme temperatures: -40ºC to 85ºC, without re-rating. Color indicators in the handle to easily see operational status at-a-glance. It is easy and reliable to use, which supports short circuit protection, overload protection. Widely used for solar panels grid system, wind and solar hybrid system and many other DC systems. The JB is a DC circuit breaker dedicated to multi string photovoltaic installations. It is used for distribution and protection the facilities from damages caused by overload and short-circuit.

Constant AMPs significantly lower, gets hot
I bought a 50A breaker to do a run test on my UPS (two 12V batteries). After running for 5 minutes at 36-37A this breaker tripped, which is well below 50A. I bought a 63A variety. That was able to carry the 37A for over an hour, but at app. 40 minutes it became too hot to touch and for the last 20 minutes I had to cool it actively with a fan as I was concerned it will melt or burn. But 63A did not trip at 37A constant current. I haven't seen specs published on these breakers, so maybe this will help someone.

Good DC Circuit Breakers/Disconnect
It took a while for these to arrive (ships from China), but the circuit breaker work as advertised. Easily mount in a DIN Rail Enclosure and are great for disconnecting solar panels (or other DC loads) for service or test and at the same time provide overload/short circuit protection for the wiring

Seems like an excellent product.
Good size connection points and good wire contacts should ensure no wiring difficulties. Smooth swithing operation. Nice tight rail mounting should insure a good installation every time.

It is installed. I did not trip it to test it (not that I have the means to) so it will have to wait for a fault to happen some day, hopefully never.
