Ungrounded DC System

SE-601 SEꢀiES (PGꢀ-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 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.
