Three Phase MSB Surge Diverters for LPZ0A/1

For industrial and commercial main switchboards

Novaris three phase MULTIMOV surge diverters are smart SPDs with a digital display providing details of surge capacity and performance. Upon switch on the display shows the product name and surge rating; after a few seconds it shows the surge capacity in percent. A segment failure will drop the percentage and activate the external alarm. Additionally, an over temperature will flash the display 000 indicating time for replacement.

  • Type 1/2 ratings
  • Segmented redundancy
  • Percentage active digital display
  • Over temperature sensing
  • All mode protection (-N model) for TT systems
  • Active remote alarm connections
