Information for further cross-connector arrangements will be provided on request.
 - Stripping length
IECEx / ATEX Terminal and Cross-Connector Arrangements:
 - cross section, American Wire Gauge
 - Tightening torque range, terminal screw
Max voltage data according to IEC/EN 60079-7 in conjunction with
protective conductor terminal blocks of the WPE-Series, (increased safety "eb"): 
 - 2 conductors with same cross-section
 - Rated conductor cross section
 - Conductor cross section flexible 
 - Contact resistance
 with rated conductor, 4 mm² 
 - Conductor cross section stranded
 - Conductor cross section solid
 - Rated current with ZQV
 - Rated voltage
Technical data according to IEC/EN 60079-7 (increased safety "eb"):
 - Rated current
 - Temperature rise with rated current 
Application Case
Intermediate - bridging one or more unconnected terminals (e.g. every 3rd terminal)
Next to a protective conductor terminal (earth) without a partition plate
Cross-connection with triple parallel
Continuous
Cross-connection with twin parallel
