the connected motor.
The values in Table 46 refer to the rated operation of the motor sizes
(motor rating, 4 pole three-phase asynchronous motor) at an ambient air
temperature of +40 °C.

The start produces currents above the rated operational current.
All enclosure types in which the Soft starter is to be installed must have the
required power loss capacity. Depending on the ramp time set and the
current limitation, this current can be present for several seconds.
The resulting heat dissipation must in this case be allowed for in the housing
design.
