Product Specifications & Features

  • Exceeds ITIC requirements by disconnecting from failing utility in under 20ms
  • Load protection with smooth, instantaneous transfer between micro and utility grid protection events, IEEE 1547 events, and power quality events.
  • Automatic sensing and control automatic separation of micro grid and utility grid during system problem and reconnection back to the utility grid when the utility system is normal
  • Offers synchronism check
  • Based on silicon controlled rectifier (SCR) technology
  • Offers necessary series protection to clear any internal faults caused by component failures
  • Normal rating is 220% of the system rated voltage per IEEE 1547 Section
  • Optional NEMA 3R enclosure



The SuperSwitch GT shall operate in conformance with the following applicable standards:

  • IEEE 1547 (standard for Interconnecting Distributed Resources with Electric Power Systems)
  • ITIC
