CHINT NWC6 Series Dry Low-voltage Shunt Capacitor

CHINT NWC6 Series Dry Low-voltage Shunt Capacitor,
is designe for power frequency AC systems up to 1000V to enhance power factor,
reduce line losses, and improve voltage quality.
Built with dry flame-retardant materials and a self-healing mechanism, it provides safe,
oil-free operation and long service life. With capacities from 5 to 40 kVar and compliance with IEC/EN 60831-1/2 standards,
the NWC6 ensures reliable performance in industrial, commercial, and power distribution systems.
