NE² MCSG

The NE² MCSG, designed with customer safety as the top priority, has obtained full type test and internal arc certification based on IEC 62271-200. Its compartmentalized structure maximizes internal arc performance, and with patented technology applied, it successfully passed the Telcordia Zone 4 seismic test.

LSC2B-PM structure, the highest safety class under IEC 62271-200

  • Separate compartments for each function and device
  • Each partition consists of grounded continuous metal barriers and shutters
  • Structure designed for easy maintenance

Proprietary Technology
