Low-voltage complete devices

Low-voltage complete devices

Low-voltage complete devices: switchboards, water-distributing devices, control cabinets.

Low-voltage complete devices are designed to receive and distribute three-phase alternating current with a frequency of 50 and 60 Hz, voltage of 0.4 kV. These devices are used to automate the work of consumers and protect them from emergency modes.

Low-voltage complete devices include a number of typical types of equipment, including:


- switchboard (intended for input, distribution, metering of electricity, protection of electrical circuits during overloads and short circuits in power installations of residential, public, industrial, administrative and other outbuildings);

- the main switchboard (designed for full or partial redundant supply of electricity, three-phase alternating current with a rated operating voltage of 380 V and a frequency of 50 Hz in public and industrial buildings);

- an input-distribution device (intended for the reception, metering and distribution of electrical energy in electrical installations of residential, public and industrial buildings);

- control cabinet (designed for switching power circuits, control circuits and control of actuators of process equipment, protection against short circuits and overcurrent).

In one low-voltage complete device, the methods of arrangement and the types of used devices, instruments and devices can be combined.
