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
Analog data provided

The SuperSwitch®GT offers the following GUI controls
• Local – will connect and reconnect when conditions are within limits.
• Off – is disconnected and semiconductors are de-energized.
• Remote – accepts “connect” and “disconnect”
commands from an external control system. If the
connect command is given it will connect and
disconnect when conditions are within limits of
the SuperSwitch®GT internal controls.
