Solid-state/mechanical switching technology
Solid-state switching
The motor starter controls the motor (two phases) with thyristors. Phase L1 is not switched
but is instead looped through from the 400 V power connection to the motor connection via
the integrated disconnecting means.
DANGER
Hazardous voltage
Can cause death or serious injury.
If the line voltage is present at the 400 V power connection of the motor starter, hazardous
Can cause death or serious injury.
If the line voltage is present at the 400 V power connection of the motor starter, hazardous
voltage may still be present at the motor starter output even if a start command has not
been issued.
When carrying out any work on the branch, make sure that you disconnect it via the
When carrying out any work on the branch, make sure that you disconnect it via the
disconnecting means.
Mechanical switching
The motor starter controls the motor (three phases) with contactors.
On device versions with a rated operating current of 0.15 - 2A (3RK13..-6KS41) RC
elements are integrated on the motor output side to dampen interference pulses.
Contact block defective
If a contact block is defective (contactor welded / thyristor failure), the motor starter cannot
shut down the motor.
If necessary, evaluate the message "Device fault" and shut down the branch on the basis of
If necessary, evaluate the message "Device fault" and shut down the branch on the basis of
this by means of an upstream contact block.
