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 1500 V dc 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
