Main Distribution board GRSh

Main switchboards of the GRSh series are intended for completing low-voltage switchgear and control cabinets at power engineering and industrial facilities. Standard devices, equipment, components for installation and connection (domestic devices, Schneider Electric, ABB) are installed in any of the cabinets of this series. The choice depends on the tasks set, the size of the switchboard and the facility. Main switchboards consist of: input cabinet(s) ШВ; sectional cabinet (in case of the GRSh design with two inputs) ШС; linear cabinets ШЛ. The main switchboard with one input consists of an input panel (ШВ) and outgoing line panels (ШЛ). The main switchboard with two inputs consists of: input panels (ШВ), outgoing line panels (ШЛ) and sectional switch panel (ШС). The GRSh boards provide the following protection: against multiphase short circuits; against single-phase short circuits; against short circuits in control and signaling circuits.
