Siemens SIMOTICS S-1FT2 - Rotating Motor Connectors

Current-carrying capacity for power and signal cables
The current-carrying capacity of PVC/PUR-insulated copper cables is speci󹪝ed for routing types
B1, B2 and C under continuous operating conditions in the table with reference to an ambient
air temperature of 40° C. For other ambient temperatures, the values must be corrected by the
factors from the "Derating factors" table.
