SYStem6

12÷36 kV
SYStem6 MV switchboards is composed by a standardized, modular and compact series of protected and internally arc-proofed panels metal-enclosed type (LSC2A-PI), equipped with SF6 insulated on-load switches and vacuum circuit breakers. Complex switchboard configurations can be realized using modular panels. Each panel and circuit is equipped with necessary mechanical interlocks and visual mimic diagram to ensure maximum safety of the operator.
