Product Description:
The RZW02.1-132-025 braking resistor is manufactured by Bosch Rexroth Indramat as part of the RZW Braking Resistors series. In an automation line, it is wired across the DC link of a servo or frequency inverter so that regenerated energy is converted into heat instead of raising the link voltage. This function is important when conveyors, hoists, or indexing tables decelerate abruptly because it protects the drive and shortens stopping times without relying on mechanical friction brakes. The resistor must be installed where the generated heat can dissipate safely without affecting nearby components.
Its continuous dissipation rating is 25 kW, enabling the module to handle regenerative energy during extended production runs. For short, high-energy events, the peak absorption rises to 132 kW. The resistor element has a resistance of 2.4 Ω, and the drive may use parallel connections only if the total external resistance does not fall below the required minimum of 2.2 Ω. During braking, the element may remain energized for up to 30 s before a mandatory cooling interval of 90 s. These operating and cooling periods create a 120-second load cycle that helps prevent excessive thermal accumulation. Connection is made through an M10 terminal that accepts copper conductors with a cross-sectional area of 70 mm², providing a low-impedance path between the inverter and the resistor bank.
The housing measures 490 mm deep, 995 mm wide, and 710 mm high, while the assembly weighs 93 kg. A thermal time constant of 100 s indicates how quickly the resistor responds to changes in thermal load, and its maximum surface temperature is 80 °C. The allowable operating factor is 25% SD, which limits the energized portion of each repeated duty cycle. With ingress protection rated at IP20, the unit is intended for installation inside a dry indoor cabinet that prevents accidental contact with internal components. The product is design version 1 and belongs to Line 2 of the RZW series.
