Switchboard panel Light Panel-70
Switchboard panels of the Light Panel-70 series are among the most demanded products of the MKC 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 MKC 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.
Design configuration
The standard Light Panel-70 panel is a welded metal structure of bent steel sections with slots for electrical equipment. The panels service is unilateral. Disconnectors, fixed switches, devices and cutters are controlled by means of drives on the facade side of the cabinet with the doors fully closed.
