Description

The PGR-2601 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 a PGG Family

Ground-Reference Module—a resistor network that limits

ground-fault current to 25 mA. The PGR-2601 is used on

ungrounded dc systems ranging from industrial 24-Vdc

control circuits to 1000-Vdc transportation systems.

beNeFitS

Sensitive setting provides a wide range of

low-level protection

Adjustable trip delay allows quick protection or

delayed response

Form A and Form B ground-fault output contacts for

operation of separate annunciation and trip circuits

Provides means for connecting to a meter

(PGA-0500) or a control system

Retains trip state when de-energized to simplify

troubleshooting

Selectable fail-safe or non-fail-safe operating

modes allows connection to shunt or

undervoltage breaker coil

No calibration required saves on maintenance cost
