.1 Number Contacts
The pole number (number contacts) important consideration when
selecting connector for certain application. The assumed conductor cross-sections
can found the derating diagram (power loss curve).
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously.Criteria for Selecting Connectors 23
2 Criteria for Selecting Connectors
2. 2.1. the connector has a
protective contact (PE), should counted separately.1: Han® 108 Fig.1 Electrical Criteria
2. For all other (not standardized) rectangular connectors, the
number poles can chosen freely.

DIN 43652 specifies the design and number contacts for only four types
of connectors. 2.2 Current
The rated current (current-carrying capacity) another selection criterion.2: Han® 3A

2. Also, certain arrangements have
become common. Usually, you must take into
account that only useful contacts are counted
