SE-703 Series - Earth-Leakage Monitor

Series: SE-703
Roll Over to Zoom
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.
