* Typical power rating at 400 VAC with cos phi=0.85. The exact value depends upon the efficiency of the drive, the motor and the entire application.

** Standardized calculated leakage current acc. IEC 60939 under normal operating conditions.

*** Normally closed thermal protector switch, 250VAC / 24VDC, 6.3A (with cos phi 0.6); reverse switching temperature = switching temp - 50K.
