Footprint braking resistors
In the table below, the different SK BR4-… footprint braking resistors are assigned to the individual
power ranges and compared to those of type SK BRU5-…. The footprint braking resistor
types/designs are different for both device series. Depending on the space available and the
respective depth in the control cabinet, the footprint braking resistors for the SK 5xxE can be mounted
flat or vertically (book size) next to the frequency inverter.
SK 5xxE with SK BR4-xxx/xxx
SK 5xxP with SK BRU5-x-xxx-xxx
Illustration 8: Footprint braking resistor designs for size 2
Both footprint braking resistor designs are UL certified and can also be installed outside the control
cabinet due to their IP40 protection class version and for better heat dissipation. The footprint braking
resistors’ lead-out connection cables must be lengthened accordingly.
Information
The connection cable lengths and short-time powers are different for the device-specific footprint
braking resistor types. For detailed information, please refer to the technical information
Chapter
5.1.2 "Technical information/Data sheets".
