Technical specifications

General

• 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 4.1.8.3.

• 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
