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.
