●
100 to 120 V AC = max. 740 mA
●
208 to 240 V AC = max. 400 mA
●
380 to 500 V AC = max. 250 mA
●
515 to 690 V AC = max. 200 mA
For permissible variation of mains voltage of ±30 %:
●
100 to 120 V AC = max. 1,200 mA
●
208 to 240 V AC = max. 750 mA
●
380 to 500 V AC = max. 400 mA

515 to 690 V AC = max. 400 mA
Current consumption
Category III according to IEC 60364-4-443Overvoltage category
The actuator controls are designed for the nominal motor power, refer to motor name plateRated power
Reversing contactors (mechanically and electrically interlocked) for AUMA power classes
A1/A2
Standard:Switchgear
Reversing contactors (mechanically and electrically interlocked) for AUMA power class
A3
Options:
Thyristor unit for mains voltage up to 500 V AC (recommended for modulating actuators)
for AUMA power classes B1, B2 and B3
The reversing contactors are designed for a lifetime of 2 million starts. For applications requiring a high
number of starts, we recommend the use of thyristor units.
For the assignment of AUMA power classes, please refer to Electrical data on actuator
