Description

The SE-601 is a microprocessor-based ground-fault relay for ungrounded dc 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. The SE-601 is used on ungrounded dc systems ranging from industrial 24-Vdc control circuits to 1000-Vdc solar and transportation systems.


Features & Benefits

  • Adjustable pickup (1-20 mA)

    Ten settings provide a wide range of low-level protection

  • Adjustable time delay (50 ms-2.5 s)

    Adjustable trip delay allows quick protection or delayed response

  • Output contacts

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

  • Analog output (0-5 V)

    Provides means for connecting to a meter (PGA-0500) or a control system

  • Non-volatile trip Memory

    Retains trip state when de-energized to simplify troubleshooting

  • Selectable contact operating mode

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

  • Microprocessor based

    No calibration required saves on maintenance cost
