Product Overview

SE-704 is a microprocessor-based ground-fault relay for resistance and solidly-grounded systems. It offers very sensitive ground-fault detection as low as 10mA and can be used on systems with significant harmonic content. The SE-704 provides feeder-level protection or individual-load protection. The output contacts can be connected for use in protective tripping circuits or in alarm indication circuits. The analogue output can be used with a PLC or a meter.
  • Adjustable pickup (10mA to 5A)
  • Adjustable time delay (30ms to 2.0s) allows quick protection and system coordination
  • Form A and B ground-fault output contacts for operation of separate annunciation and trip circuits
  • Analog output (0-5 V & 0-1 mA)
  • CT-Loop monitoring alarms when CT is not connected
  • Selectable contact operating mode
  • Harmonic filtering eliminates nuisance tripping
  • Non-volatile trip memory retains trip state when de-energized to simplify troubleshooting
