Frequency converters 3×400 V and 3×500 V with power up to and including 18.5 kW feature a built-in braking transistor, which enables the connection of an additional braking resistor.

All other frequency converters are equipped with a braking transistor only if this was specified while ordering. This is essential, as the braking transistor is installed at the stage of production and cannot be added later.
