Braking resistors for chassis format Siemens
![](https://pzip.ru/Images/Siemens/cat/P_D011_XX_00043i.jpg)
Обзор
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 arrangement enables the resulting heat losses to be dissipated, thereby allowing a corresponding reduction in the level of air conditioning required.
2 braking resistors with different rated and peak power values are available for chassis format units.
The braking resistor is monitored on the basis of the mark-space ratio. A temperature switch (NC contact) is also fitted. This responds when the maximum permissible temperature is exceeded and can be evaluated by a controller.
