ABB 200 - 4000A Digital Static Transfer Switch

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 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
