AUMA power class for
switchgear 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.

2.2. Short description
Part-turn actuator Definition in compliance with EN ISO 5211:
A part-turn actuator is an actuator which transmits a torque to the valve for less than
one full revolution.It need not be capable of withstanding thrust.
AUMA part-turn actuators are driven by an electric motor. A handwheel is provided
for manual operation.Switching off in end positions may be either by limit or torque
seating. Controls are required to operate or process the actuator signals.
Actuator controls The AUMA MATIC actuator controls are used to operate AUMA actuators and are
supplied ready for use.The controls can be mounted directly to the actuator but also
separately on a wall bracket.The electro-mechanical version of the AUMA MATIC
controls includes switchgear for control in OPEN - CLOSE duty and a logic for various
indications via contacts
Local controls Operation (via push buttons), setting and indication can be performed directly at the
controls (contents of these instructions).
