Information for further cross-connector arrangements will be provided on request.
Cross-connection with twin parallel
Continuous
Next to a protective conductor terminal (earth) without a partition plate
Cross-connection with triple parallel
Application Case
Intermediate - bridging one or more unconnected terminals (e.g. every 3rd terminal)
- Conductor cross section solid
- Stripping length
IECEx / ATEX Terminal and Cross-Connector Arrangements:
