For all other (not standardized) rectangular connectors, the
number poles can chosen freely.1.2: Han® 3A

The rated current (current-carrying capacity) another selection criterion. the connector has a
protective contact (PE), should counted separately.
DIN 43652 specifies the design and number contacts for only four types
of connectors. Usually, you must take into
account that only useful contacts are counted. 2. 2.
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously. Also, certain arrangements have
become common.
.1 Number Contacts
The pole number (number contacts) important consideration when
selecting connector for certain application.1 Electrical Criteria
