The BRB series resistors are resistor boxes that assembled with wirwound braking resistors and can be suitable for rugged applications with very high power rating. This resistor group is designed for heavy duty and harsh conditions such as elevators, cranes or for braking of big electrical motors. This type has capability to withstand overload for a long time without any damage. Furthermore the power limits indicated ensure that the temperature doesn't damage other components nearby. It also ensures stability and reliability.
