Product Description:
The RZW02.1-075-060 is a braking resistor module manufactured by Bosch Rexroth Indramat within the RZW Braking Resistors series. It is installed on the DC link of Rexroth drive systems to convert regenerative motor energy into heat, preventing overvoltage during deceleration or vertical load lowering. The unit belongs to mechanical design code 1 and is supplied for line code 2 applications that require controlled thermal dissipation rather than energy feedback to the power supply. This arrangement allows the drive to manage regenerated energy when a connected motor acts as a generator.
The resistor has a continuous dissipation rating of 75 kW and a fixed resistance of 5.3 Ω. Conductors connect to terminals sized for a line cross section of 70 mm², keeping voltage drop low during high-current peaks. The IP20 enclosure permits ventilation while helping prevent accidental contact with internal components. The housing has an overall height of 960 mm and a depth of 490 mm, allowing installation in tall control cabinets without exceeding common panel depths. Its thermal mass supports a 120-second load cycle with a permitted on-time of 72 seconds. A mandatory off-time of 48 seconds allows the resistor to cool before the next braking event and prevents excessive temperature buildup in the internal elements.
The module has a maximum operating factor of 60% SD, and its surface temperature remains at or below 80 °C during operation within that duty cycle. A width of 795 mm provides space for the heat-emitting plates, while the unit’s mass of 102 kg contributes substantial thermal inertia. The resistor has a thermal time constant of 100 seconds, which moderates the rate at which its temperature changes under load. The minimum connectable resistance is 3.75 Ω, allowing parallel units to be arranged without falling below the drive system’s resistance limit. The aluminum resistor elements dissipate stored energy during each energization period and cool during the required interval between braking events.
