20. IED case and IED plug-in unit

For safety reasons, the IED cases for current
measuring IEDs are provided with automatically
operating contacts for short-circuiting the CT
secondary circuits when a IED unit is withdrawn
from its case. The IED case is further provided
with a mechanical coding system preventing
current measuring IED units from being inserted
into a IED case for a voltage measuring IED unit
and vice versa, i.e. the IED cases are assigned to
a certain type of IED plug-in unit.
21. Selection and ordering data
The IED type and serial number label identifies the
protection IED. The label is placed above the HMI
