Motor Control Center Medium Voltage - VR MClad

The Motor Control Center Medium Voltage VR MClad line of VR Painéis are composed of air-insulated modular series with metallic compartments of metal-clad type, intended for protection, maneuver and control of medium voltage motors for voltage class up to 15kV. These sets are assembled and tested in factory meeting the requirements of standard IEC 62271-200 and NBR 14039. The structure of the set is composed of folded and bolted profiles (4 folds forming an Omega type geometry), with the highlight to the following items:

. Structure consisting of 5 metal compartments;
. Extractable circuit breakers or contactors;
. Vacuum switching technology;
. Capacitors bank;
. Protection Relays;
. Access to the front or rear cable compartment;
. High safety in operation;
. Reliability and service continuity.

Designed for use in various fields of electrical installations, its main applications are:
. Chemical and Petrochemical Industries;
. Stations of water treatment and sewage;
. Sugar and alchool plants.
