These resistors belong to the lower power ratings of the aluminium housed types. They are mostly used in DC-links for charging and de-charging and in small inverter drives systems as brake resistor. CCH can be mounted on a (water) cooled plate to increase the nominal power. CAR has cooling fins to optimize heat transfer to the ambient air. The nominal power ranges from 60-440W, maximum working voltage is 690VAC/850VDC, pulse load values depend on Ohmic value and range between 4 to 25 x Pnominal at a 5 seconds square load.
