Protection Relays and Controls Ungrounded DC System SE-601 SERIES (PGR-2601) DC Ground-Fault Monitor 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 Modulea 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 FEATURES BENEFITS Adjustable pickup Ten settings provide a wide range of (1 - 20 mA) low-level protection Adjustable time delay Adjustable trip delay allows quick protection or (50 ms - 2.5 s) delayed response Form A and Form B output contacts for operation of Output contacts separate annunciation and trip circuits Analog output Provides means for connecting to a meter (0 - 5 V) (PGA-0500) or a control system Simplified Circuit Diagram Non-volatile trip Retains trip state when de-energized to simplify Memory troubleshooting + Selectable fail-safe or non-fail-safe operating Selectable contact modes allow connection to shunt or undervoltage A operating mode breaker coil SE-GRM SERIES UNGROUNDED Microprocessor based No calibration required saves on maintenance cost GROUND-REFERENCE SUPPLY MODULE Accessories - A SE-GRM Series Ground-Reference Module Required accessory, used to connect the SE-601 DC Ground-Fault Monitor to the SE-601 DC bus. (DC Ground-Fault Monitor) L1 PGA-0500 Analog % Current Meter L2 Optional panel-mounted analog meter displays ground-fault current as a percentage of 22 mA.
