CHINT NXCC Capacitor Contactor,
is a specialize device designe for safe and efficient switching of low-voltage capacitor banks in power factor correction systems.
With rate operational voltage up to 690 V and current ratings from 25 A to 170 A,
it minimizes inrush current using pre-charge resistors to protect capacitors and extend service life.
Built to IEC/EN 60947-4-1 standards, the NXCC series ensures reliable performance in reactive power compensation,
offering stable operation even under demanding industrial conditions.
