Braking resistors

The excess energy of the DC link is dissipated via the braking resistor.

The braking resistor is connected to a braking module. The braking resistor is positioned

outside the cabinet or switchgear room. This enables the resulting heat loss around the

Basic Line Module, Smart Line Module, Active Line Module, or Motor Module to be

dissipated, thereby reducing the amount of air conditioning required.

Resistors with a rated power (continuous power) of 25 kW and 50 kW are available.

A thermostatic switch monitors the braking resistor for overtemperature and issues a signal

on a floating contact if the limit value is exceeded.
