Input and distribution devices of VRU series

Input and distribution devices (VRU) are designed for receiving, distributing, and metering electrical energy in electrical installations of residential and public buildings, as well as for protecting distribution and group circuits outgoing from VRU against overloads and short circuits.

VRU are connected to power supply electrical networks with a rated voltage of 380/220V AC at 50Hz with a solidly grounded neutral.

VRU devices are manufactured in accordance with TR CU (Technical Regulation of the Customs Union) requirements, working design documentation, and GOST 22789-94 regarding low-voltage switchgear and controlgear assemblies requirements.
