SE-601 Series - DC Ground-Fault Monitor

Roll Over to Zoom
Operates on DC ungrounded systems ranging from industrial 24- Vdc control circuits to 1000-Vdc solar and transportation systems. It provides sensitive ground-fault protection without the problems associated with nuisance tripping. Ground-fault current is sensed using an SE-GRM Series Ground-Reference Module—a resistor network that limits ground-fault current to 25 mA.
