The pole number (number contacts) important consideration when
selecting connector for certain application. the connector has a
protective contact (PE), should counted separately. The assumed conductor cross-sections
can found the derating diagram (power loss curve).1. Usually, you must take into
account that only useful contacts are counted.1 Electrical Criteria
