570 Hybrid Surge Protective Device

A true hybrid device offering a coordinated multi-stage system of suppression, integrating the fast response time of the SAD (Silicon Avalanche Diode) modules with the high-energy capability of the MOV modules. Superior clamping at surge current ratings up to 375kA per mode or 750kA per phase.

  • 570 (Hybrid) builds upon the industry standard 560 Series.
  • Patented component level monitoring — including neutral to ground.
  • Unique sand-packed silver fuse network UL Rated at 200kAIC for safety.
  • All surge suppression components used are computer tested and matched. SADs are matched to +/- 1% and MOVs are matched to 1 volt for optimum reliability and long life.
  • Highest surge current capability and survivability in the industry.
  • Built-In-Test feature standard.
  • 10-year warranty on parts and 5-year on-site labor, backed by Emerson Power Service.
  • True, coordinated multi-staged system of suppression.
  • Lowest UL 1449 clamping voltages achieved.
  • Smaller enclosure size allow for easier installation for hybrid system./li>
