SE-703 Series - Earth-Leakage Monitor

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.

FEATURES

BENEFITS

Adjustable pickup
(25 - 500 mA)

Adjustable trip setting provides a wide range of low-level protection and system coordination

Adjustable time delay
(50 - 500 ms)

Adjustable trip delay allows quick protection and system coordination

Output contacts

Form A and Form B ground-fault output contacts for operation of separate annunciation and trip circuits

Analog output
(0 - 5 V)

Allows for connecting an optional meter (PGA-0500) or control system

CT-Loop monitoring

Alarms when CT is not connected

Selectable contact operating mode

Selectable fail-safe or non-fail-safe operating modes allow connection to shunt or undervoltage breaker coil

Harmonic filtering

Eliminates nuisance tripping

Non-volatile trip memory

Retains trip state while de-energized to simplify troubleshooting

Microprocessor based

No calibration required, saves maintenance cost

Universal
power supply

Allows operation in application where one side of PT is faulted, provides flexibility for numerous applications
