Low-voltage switchgear MNS/GCS/GCK
The incoming feeder cabinet of the switchgear adopts a drawer-type switch, which can accommodate high-current switches with strong breaking capacity. The outgoing feeder units are also drawer-type, featuring clear operational labeling and facilitating convenient maintenance and replacement. The incoming cable connection can be either top-in or bottom-in, and both the base plate and the top plate are equipped with ventilation holes for excellent heat dissipation. This equipment is widely used in substations, residential communities, high-rise buildings, and other similar applications.
