Physical hardware

The IED consists of two main parts: plug-in unit and case. The plug-in unit content
depends on the ordered functionality.

1) The 0.2/1 A input is normally used in applications requiring sensitive earth-fault protection and featuring
core-balance current transformers.
The rated input levels are selected in the IED software for phase current, residual
current and residual voltage. The binary input thresholds 18...176 V DC are selected
by adjusting the IED's parameter settings.
