The switchgear used in the actuator controls (reversing contactors/thyristors) are
classified according to AUMA power classes (e.g. A1, B1, ....). The power class
defines the max. permissible rated power (of the motor) the switchgear has been
designed for. The rated power (nominal power) of the actuator motor is indicated in
kW on the motor name plate. For the assignment of the AUMA power classes to the
nominal power of the motor types, refer to the separate electrical data sheets.
For switchgear without assignment to any power classes, the actuator controls name
plate does not indicate the power class but the max. rated power in kW.
