CT/Self-powered – No auxiliary supply voltage needed
Designed for harsh environment
Compact form factor
The WI Line devices are self-powered – The protection relay does not need supply voltages for Ring Main Units (RMUs).
The primary application of WI Line devices is Feeder Protection (also as backup) that does not need supply voltage.
