Operates on AC solidly grounded and AC resistance grounded systems.
The SE-703 is a microprocessor-based ground-fault relay for resistance and
solidly-earthed systems. It offers sensitive ground-fault detection as
low as 25 mA and can be used on systems with significant harmonic
content. The SE-703 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 analog output can be
used with a PLC or a meter. The SE-703 is specifically designed to be
Australian AS/NZS 2081 compliant.
