Switchboard panel Light Panel-70

Switchboard panels of the Light Panel-70 series are among the most demanded products of the MKS Group of Companies. Light Panel-70 is designed to pack 380/220 V three-phase AC 50 Hz frequency switchgears with a blind neutral. They are used for electric energy reception and distribution, outgoing lines protection from overloads and short-circuit currents. The quality and reliability of the Light Panel-70 largely depends on the correct and careful choice of every component, and the MKS Group of Companies pays a great attention to it. That is why only certified components produced by the leading domestic and foreign manufacturers are used in at the Light Panel-70 production.
