Low-voltage complete device (LVDD) input-distribution panel is designed for receiving, metering and distribution of electrical energy with voltage 230/400 V 50 Hz with earthing system TN-S or TN-C-S, as well as for protection of lines and equipment from overloads, short-circuit currents and earth leakage currents
The switchgears are manufactured in enclosures of cabinet or box type from sheet steel with thickness from 0,75 to 2,0 mm.
In addition to the function of electric power distribution the switchboard ShchVR-40-SKV-Vpch-1(m/r) performs frequency-regulated control of motor rotation speed, are made in the form of mechanically unconnected shells (cabinet and drawer), Inside the VHR drawer the frequency converter (hereinafter - IF), output filter, contactor and terminal blocks are located.
The design of the switchgear and controlgear box provides convenience of installation and safety of maintenance of components and conductors.
