Main switchboards main switchboards:

Main switchboards is a cabinet-type module that houses the receiving and distributing electrical equipment and equipment that protects networks from short circuits and overloads. The dispensing equipment is functional with respect to 3-phase networks with an alternating voltage frequency of 50 Hz and a power of 220, 380 V.

The design of the main switchboard includes panels:

• introductory;
• sectional;
• distributive.

The role of input and sectional modules is performed by switches – automata or disconnectors. Roll-out introductory and sectional automata allow for a visible gap. According to the specifics of the operation of the main switchboard, the machines can be equipped with:

• power drives;
• auxiliary remote releases, contributing to the implementation of an automated reserve input scheme;
• accessory signal contacts.

The distribution panels are powered by the main bus wire. The technicality of the main busbar and hardware equipment is selected in accordance with the power consumption or source.
