Braking resistor
A braking resistor is a device in which the current generated by the fan motor during
braking is converted into heat (the motor goes into generator mode during braking). This is a
component closely connected to the frequency inverter. It has a IP 65 class protection and a
resistor in the radiator design.
SzA-FCK cabinet has braking resistors mounted on the side of the enclosure, SzA-FCP has
connected resistors which are mounted on bulkheads on the fan side.
