SYSclad MV switchboard is composed by a standardized and modular series of panels metal-clad type (LSC2B-PM), with air insulated busbar system.
The panels are equipped with withdrawable WL-r series vacuum circuit breakers.
Each panel and circuit is equipped with necessary mechanical interlocks to ensure maximum safety of the operator.
All the functional units of the switchgear are separated, to guarantee the internal arc withstand according to IEC 62271-200 standards.
