Braking resistors are used for lifting and driving gears, elevator drives, conveyors, drives on manipulators as well as all drives where fast speed changes are to be controlled and the excess energy is not consumed by the loads or losses of the machine. Resistors for smaller ratings can be installed together with the other equipment in the switchgear unit. Resistor units within a small power range are available in IP65. Due to the heat formation, resistors for larger ratings often have their own casing and are installed separately. The possible protection degree are from IP00 – IP23.
Brake resistors specifically for railway purposes can be found here.
