The CLH31A and CLH41A braking resistors with support plate are supplied as a combination of support plate and integrated braking resistor. There is a selection of braking resistors with different ratings for each support plate.

In certain circumstances, braking resistors mounted in the submounting may not reach the current-carrying capacity specified in the table at 100% cdf. The specifications for the nominal power of the inverter can be observed in submounted operation at 4 kHz, 40 °C and 400 V.
