SYStem6 medium voltage switchboards are crafted with a standardized, modular, and compact design, making them suitable for a range of complex electrical configurations. The switchboards boast an enclosure that is both protected and arc-proof, classified as LSC2A-PI. Key components include SF6 insulated on-load switches and vacuum circuit breakers. Designed to ensure the operator`s safety, each panel is outfitted with mechanical interlocks and visual mimic diagrams. The switchboards cover a rated voltage spectrum of 12 to 36 kV, with power-frequency withstand voltage ratings up to 70 kV and lightning impulse withstand voltages reaching 170 kV. They operate at frequencies of 50-60 Hz, with main bus bar currents up to 1000 A and functional units up to 630 A or 1000 A. The switchboards can withstand short-circuit currents of up to 25 kA for specified durations and feature internal arc protection up to 16 kA for 1 second, with protection degrees of IP2X internally and IP3X externally.
