2. For all other (not standardized) rectangular connectors, the
number poles can chosen freely. 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.1 Electrical Criteria
