Braking resistor

Excess energy in the DC link is dissipated in the braking resistor.

The braking resistor is connected to the Braking Module. The braking resistor is positioned outside the cabinet or switchgear room. This enables the resulting heat loss to be removed from the area of the Power Modules. The level of air conditioning required is therefore reduced.

A temperature switch (NC contact) is fitted. This responds when the maximum permissible temperature is exceeded and can be evaluated by a controller. The maximum permissible cable length between the Braking Module and braking resistor is 100 m.
