Power range from 100W to 5kW, a popular and economically type of brake resistor capable of solving many brake resistor jobs.
The resistor components consist of fully welded wire wound ceramic resistors, wound on corderite, which is a type of ceramic with a very high resistance to temperature changes.The wire is coated with aluminium phosphate to protect the wire and conduct the heat developed in the wire on to the ceramic core. Aluminium-phosphate is stable at 500°C.
