When the speed reference of a frequency converter is reduced, the motor acts as a generator and the frequency converter brakes. When a motor acts as a generator, it
supplies energy to the frequency converter which is collected in the DC link. The function of the brake resistor is to provide a load on the DC link during braking, thereby ensuring that the braking power is absorbed by the brake resistor.

The steel grid brake resistor is steel grid housed and consists of multiple elements. This brake resistor is suitable for pulse loads between 10 and 20 times the nominal load,
suitable for frequent braking applications such as cranes, hoists and elevators. It is supplied in an IP20 enclosure with cable glands and has a built-in temperature switch. 

The steel grid brake resistors are designed for horizontal mounting only.
