NXMNLE series transparent shell residual current action circuit breaker

Function and use

NXMNLE series residual current operated circuit breaker series, its main function is to provide indirect contact protection against fatal personal electric shock, and to provide protection against electrical fires caused by ground fault current, such as insulation damage, etc. It also provides protection against overload, short circuit and under-voltage of the line, and can also be used for infrequent switching of the line.
