Where the inverter contains a built-in braking unit and the maximum braking torque is 50% a braking resistor is incorporated .  
​The Powtran braking unit is mainly used in the inverter controlled motor drive to drop speed, braking positioning, hoisting and declining.

A wire wound resistor is a resistor where a wire with a high-resistivity is wrapped around an insulating core to provide the resistance.
The resistor is a two-terminal electrical device that is used in electrical circuits to resist the flow of electrical current to serve amplification or switching requirements.
The assembly is protected with a layer of paint, molded plastic or an enamel coating baked at high temperature.
