SE-701 Ground-Fault Monitor
Functions:
- Ground-fault protection for resistance- and solidly 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
- Five year warranty
Manuals:
Typical Applications:
- Used on feeders, motors, generators, heating cable, SCR-controlled heaters, and ASD's
- Retrofit and upgrade applications using existing CT's
Minimum System Components:
The SE-701 requires an EFCT-series current sensor or a 1- or 5-A-secondary CT.
IEEE Device Numbers:
50G, 50N, 51G, 51N
Watertight Cover
Allows relays to be used in a wet environment. NEMA 4 rating. Shown mounted on the MPU-16A.
Panel-Mount Adapter
Panel mount an SE-601 or SE-70X-series ground-fault monitor.
Voltage Clamp
Protects the EFCT input on the SE-701, SE-703, MPU-32, and FPU-32 when a current transformer other than the EFCT-1, EFCT-2, or EFCT-26 is used.
