Physical hardware

The protection relay consists of two main parts: plug-in unit and case. The 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.
Rated values of the current and voltage inputs are basic setting parameters of the
protection relay. The binary input thresholds are selectable within the range 16...176
V DC by adjusting the binary input setting parameters.
See the installation manual for more information about the case and
the plug-in unit.
The connection diagrams of different hardware modules are presented in this manual.
