Tips: Features of miniature circuit breaker

The rated short-circuit breaking capacity of the micro circuit breaker is high, and some rated current levels can reach more than 10KA.
MCB breaker has a double wiring function, which can easily connect a standard bus bar and flexible wire.
Mini circuit breaker is a combined terminal block with finger protection and higher safety.
With energy storage mechanism operation, the contacts close quickly, which overcomes the adverse effects caused by the speed of manual operation of the handle, and improves the service life of the product.
A variety of accessories to choose from, and a modular and flexible combination, user installation is very convenient.
The shell and some functional parts are made of high flame-retardant, high temperature resistant and impact-resistant plastics.
High current limiting coefficient and economical price.

Very nice!

The miniature circuit breaker worked as expected. Easy to install in DIN track housing for disconnecting solar panels for service or testing while providing overload or short circuit protection for the line. Very nice MCB!
