Solar DC/AC MCB miniature circuit breaker
- The Solar Miniature circuit breaker is assembled in the solar system, it can protect the system.
NL7-63 DC MCB have protective function as shortage as overload, and are used in lighting distribution system in commerce and dwelling, and protect fractional electric motors.
And they also have many merits of high protective grade(up to IP20), high breaking capacity, reliable sensitive action, convenient, multi pole assembling, long life ect.
They are mainly adapted to the circuit of AC 250V in single pole, 415V in double, three, four poles for protecting overload and short circuit. Mean while, they are also used in
turning on or off the electric apparatus and lighting circuit under the normal conditions.
