Description
EATON Transformer Relay, Series: ETR-5000, 40 to 250 V AC, 19 to 300 V DC Supply, 5 A, 8 Inputs, 9 Outputs, Digital Input, LCD Display, Flush Mounting, -4 to 140 deg F, Aluminum, 8.06 in L x 9.72 in W x 8.7 in H Dimensions
Features:
- An unrestrained differential element provides fast tripping on heavy internal faults to limit catastrophic damage to the transformer and minimize risks to the remainder of the power system
- Instantaneous overcurrent elements allow quick clearing of severe internal or external (through) faults
- Front panel LCD display with background illumination allows for wide angle viewing in all light conditions and 14 programmable LEDs provide quick and easy visual display of power on, mode of operation, alarm and trip indication
- Maintenance mode improves safety by providing a simple and reliable method to reduce fault clearing time and lower incident energy levels at energized panels
- Complete protection and control in a single compact case reduces panel space, wiring and costs
- Integral test function reduces maintenance time and expense
- Zone selective interlocking improves coordination and tripping time and saves money compared to a traditional bus differential scheme
- Trip and event recording in non-volatile memory provides detailed information for analysis and system restoration, reducing trouble shooting time and maintenance costs
- Breaker trip circuit monitoring improves the reliability of the breaker operation
- 4 V inputs provide 3 ph voltage protection and metering information as well as an independent 1 ph voltage input
- 5/1 A phase current, 0.5/0.1 A sensitive ground current
- Modbus/DNP3 TCP over LC duplex fiber optic Ethernet communication
- Removable terminals, 1 zone interlocking, URTD interface
Applications:
Small, Medium and Large Two Winding Power Transformer
