1. the connector has a
protective contact (PE), should counted separately.1 Electrical Criteria
2.
DIN 43652 specifies the design and number contacts for only four types
of connectors.

The rated current (current-carrying capacity) another selection criterion. Also, certain arrangements have
become common.
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously. Usually, you must take into
account that only useful contacts are counted. 2.Criteria for Selecting Connectors 23

2.1 Number Contacts
The pole number (number contacts) important consideration when
selecting connector for certain application.2: Han® 3A

2. For all other (not standardized) rectangular connectors, the
number poles can chosen freely.
