Features and functions
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.
