SE-704 Earth-Leakage Monitor
Functions:
- Ground-fault protection for resistance-grounded three-phase systems
- Ground-fault protection on single-phase systems
- Main, feeder, or load protection
- Can reduce equipment damage and down time
Features:
- Microprocessor based - recalibration not required
- DFT (harmonic) filter prevents false operation
- Compatible with adjustable-speed drives and soft starters
- Self-test function
- 0- to 5-V analog output for external metering
- Selectable fail-safe (undervoltage) or non-fail-safe (shunt) operating mode
- Remote reset and indication
- Non-volatile trip memory
- Current-sensor verification
- DIN-rail, surface, and panel mounting
- Ground-fault trip level is 10 to 500 mA
- Five year warranty
Typical Applications:
Used on feeders, motors, generators, heating cable, SCR-controlled heaters, and ASD's.
Minimum System Components:
The SE-704 requires an SE-CS30-series current sensor.
