3.1.2.1  ECG in 30 mm height 
Typical values for C
ombi-Wiring terminals of ECG with 30 mm height are: 
a)  Single-core cables 
These should have a cross section of 0.5mm² at least and 1.5 mm² 
at most for the horizontal plug. 
When using I
nsulation Displacement Contacts (IDC)  cables should 
have a maximum cross section of 0,5 mm² 
b)  Multi-core cables 
horizontal plug 
These should have a cross section of 0,5 mm² at least and 1 mm² at 
most. 
Multi-core cables can be inserted directly into the horizontal plug 
terminals. 
Ferrules may be used but they are not essential. 
IDC 
Multi-core cables with a cross section of 0,75 mm² can be used for 
direct wiring with IDC.
3.1.2.2  ECG in 21 mm height 
Typical values for C
ombi-Wiring terminals of ECG with 21 mm height are: 
c)  Single-core cables 
These should have a cross section of 0,5 mm² at least and 1 mm² at 
most for the horizontal plug. 
When using I
nsulation Displacement Contacts (IDC)  cables should 
have a maximum cross section of 0,5 mm² 
d)  Multi-core cables 
horizontal plug 
These should have a cross section of 0,5 mm² at least and 1 mm² at 
most. 
Multi-core cables can be inserted directly into the horizontal plug 
terminals. 
Ferrules may be used but they are not essential. 
IDC 
Multi-core cables with a cross section of 0,75 mm² can be used for 
direct wiring with IDC.
3.1.3  Release of Contacts 
3.1.3.1 WAGO 250 
Release the contact by using the release latch. 
3.1.3.2  WAGO 251 – IDC 
Release the contact by pulling the cable upwards. 
This process can be repeated up to 10 times (depending on the 
manufacturer) without damaging the terminal. For further details please 
refer to the data sheets of the manufacturers.
