Application
Case
A - Continuous no difference between one or two cross connections
- Contact resistance top level
with rated conductor, 2,5 mm²
- Contact resistance top to lower
with rated conductor, 2,5 mm²
- Contact resistance lower level
with rated conductor, 2,5 mm²

- Rated current
IECEx / ATEX Terminal and Cross-Connector Arrangements:
Max voltage data with ZQV 4/... according to IEC/EN 60079-7 in conjunction with
protective earth terminal blocks of the WDK PE-Series, (increased safety "eb"):
- Rated current with ZQV
- Temperature rise with rated current
C - Adjacent – separated by an end plate no difference between one or two cross-connections
D - Intermediate - bridging one or more unconnected terminals (e.g. every 3rd terminal) no difference
between one or two cross connections
E - Next to a protective conductor terminal (earth)
F - Next to a protective conductor terminal (earth) separated no difference between one or two cross-
connections
Information for further cross-connector arrangements will be provided on request.
