Information
Braking resistor
If required, other versions or installation variants for external braking resistors can be provided.
Braking resistor assignments
The braking resistors provided by NORD are directly tailored to the individual devices. However, when
external braking resistors are being used, it is usually possible to select between 2 or 3 alternatives.
Note: The internal braking resistor (SK BRI4-) cannot be retrofitted! The resistor must be taken into
consideration when ordering the frequency inverter. In this case, the frequency inverter is given a
separate material number and marking –BRI at the end of the type key (for example
SK 180E
-151-340-B-C-
BRI
).
