DC Miniature Circuit Breaker
DC miniature circuit breaker can have rated working voltage up to DC 1000V.
This circuit breaker adopts special arc extinguishing and current limiting system, which can quickly disconnect the fault current of DC distribution box and protect important components in solar power generation system.
Widely used in PV, homes, workshops, hotels, shopping malls, power stations, etc.
package includes:
- 1 x DC Circuit Breaker
- 1 x Standard DIN Rail(100x35mm)
Strong Temp Adaptability
- The outershell is made of flame retardant material
- Meet the application requirements of various occasions, and can operate reliably in harsh environments.
Adjustable Installation Buckle
- Suitable for 35mm DIN rail, easy to install and hard to fall off.
Electromagnetic Release
- When the circuit fails, excessive current is generated, and the circuit breaker can quickly cut off the power supply to realize short-circuit protection.
Connection
- Tightening Torque: 2.5 N.m
- Copper Cables Rigids: 1-25 mm²
- Copper Cables Flecibles with freeule: 1-16 mm²
- Cu/Al Terminal: 50 mm²
- Ring tongue terminal screw connection: ø5 mm

excellent breaker, build quality is very good. one thing to note is that these do not have pre-defined polarity ( like others I have used ). you have to make sure top and bottom are the same ( hopefully an obvious observation ). I like these better than others I have used for DC projects ( solar ). Some have questionable ratings, these I don’t worry about.

I'm using this for switching and overload protection for DC current coming off battery connection at my solar charge controller.It feels nice and solid on the outside, and the hardware to lock down the connections seems okay. Not sure with bare Copper wire how the dissimilar metals will play together long-term, but I'm using this for a mostly seasonal application. The mounting rail feels like pretty thin Aluminum, so not sure how long that would hold up.It seems to be working fine, but I have not tried to do a load test up to rated amperage to trip the circuit breaker. I also put an inline fuse in that circuit, so hopefully at least have "enough" protections. ðŸ¤

It was easy to loosen the screws in the back and place it in to replace the old one that had overheated and no longer working.

The LANGIR DC Circuit Breaker 2 Poles 1-63A 500V was used to provide a disconnect of two Solar Panels wired in series into a Solar Charge Controller. The quality of the breaker seems very good and it worked well for my purposes. I would recommend it for any similar use.

I needed a way to disconnect my solar panels and my battery in my camper from the controlling unit so I could remove the battery and shut the system down in the winter. These worked perfect for that. The camper should have come from the factory with these already installed since the camper came with solar panels, but it didn't. Just a way to save a few dollars.
