Contact rating
depending on the
temperature
The "Technical data" tables for plug connectors (→ "Gearmotors" catalog) lists electrical
current values for the maximum permitted contact load (= max. contact load) of the plug
connectors. These current values are valid for ambient temperatures of up to max. 40
°C (104 °F). Higher ambient temperatures apply for reduced current values. The follow-
ing illustration shows the permitted contact load as a function of the ambient
temperature.
