1 Number Contacts
The pole number (number contacts) important consideration when
selecting connector for certain application. Also, certain arrangements have
become common.1 Electrical Criteria

DIN 43652 specifies the design and number contacts for only four types
of connectors. the connector has a
protective contact (PE), should counted separately.1.1. The assumed conductor cross-sections
can found the derating diagram (power loss curve). 2.1: Han® 108 Fig. 2. Usually, you must take into
account that only useful contacts are counted.

2.2 Current
The rated current (current-carrying capacity) another selection criterion. For all other (not standardized) rectangular connectors, the
number poles can chosen freely.
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously
