Product Details:


Product Description

Specification :


  • 200–1200A
  • 480 VAC, 3-phase, 3 or 4-wire (neutral not switched), 60Hz
  • 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 microgrid 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
  • Communications capabilities through relays and modbus RTU (RS485) or modbus TCP/IP
  • Easy interface to a SCADA system via modbus RTU (RS485) or modbus TCP/IP
  • Optional NEMA 3R enclosure
