Usually, you must take into
account that only useful contacts are counted.
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously. The assumed conductor cross-sections
can found the derating diagram (power loss curve).2 Current
The rated current (current-carrying capacity) another selection criterion.
DIN 43652 specifies the design and number contacts for only four types
of connectors. 2.1: Han® 108 Fig.Criteria for Selecting Connectors 23
