Product description

SMGK-F fire-fighting control and protection of switching equipment is mainly used for AC 50Hz (60Hz), rated voltage to 690V, rated current from 0.25A to 125A fire protection system, And can realize "alarm + tripping" by connecting, carrying and breaking the current under abnormal conditions (such as short-circuit current) under the current condition.

The main parameters of the main circuit and accessories modules with SMGK-45 basic type.

Model and meaning

Product type
