ZORC
stands for Zinc Oxide (arrestor), Resistor (and) Capacitor.

ZORC is a unique high frequency transient over-voltage surge suppressor for the protection of motors and transformers from steep wave-front, short rise time, high magnitude spikes, surges and other transient over-voltages generated by switching, lightning and other sources

  Key Benefits:                       

  • Eliminates inter-turn insulation failures,
  • Extends the life of machine insulation,
  • Eliminates multiple pre-strike and re-strike transients associated with vacuum and other switchgear,
  • Provides comprehensive Insulation Co-ordination at all practical surge magnitudes and rise-times,
  • Reduces direct and indirect costs of insulation failures,  and 
  • SAVES MONEY
