Depending on the project, the switchboard protects users from overvoltage and power surges in the network via an automatic circuit breaker. The distribution board protects against overloads and short circuits in three-phase networks with a voltage of 230/400V and a frequency of 50 Hz and is also used for rapid circuit switching. The distribution board is used to equip transformer substations and input devices for industrial enterprises, and residential and office buildings. Operating conditions for the distribution boards: absence of explosives or gases and vapors that corrode metal and insulation, conductive or explosive dust, and additional heating.
Input and distribution units
The input and distribution unit is a low-voltage electrical device with an apparatus that provides input, distribution, and metering of electrical power, as well as control and protection of outgoing distribution and branch electrical circuits in residential and public buildings, which is installed as functional blocks in one or more mechanically and electrically connected panels or in a single cabinet, depending on the type of building.
Distribution boards calculate the electricity consumption via meters installed inside. The product name contains the type of energy metering devices. For example, the distribution board-2 is designed to connect 2-phase meters, and the distribution board-3 is suitable for 3-phase meters.
The distribution boards calculate energy consumption and protect electrical equipment from overloads, short circuits, and prevent power system failure. The device is suitable for any premises, such as residential (apartment blocks, cottages), administrative (schools, hospitals, offices), and industrial plants.
