Input panel ShchV-1
The panel is designated to input, protect against impulse lightning overvoltages, and record electric power consumption of three feeders of three-phase voltage depending on the package.
Main functions:
- remote switching-off feeder;
- manual selective switching-off feeders;
- protecting input and output circuits against overloads and short circuits;
- recording electric power consumption on each feeder;
- monitoring and diagnosing panel’s components;
- fault light indication.
