For all other (not standardized) rectangular connectors, the
number poles can chosen freely. 2.
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously.1 Number Contacts
The pole number (number contacts) important consideration when
selecting connector for certain application.2 Current
The rated current (current-carrying capacity) another selection criterion. Also, certain arrangements have
become common. 2.2: Han® 3A
