The RZW02.1-004-060, Bosch Rexroth Indramat, RZW Braking Resistors series braking resistor delivers efficient kinetic energy management by converting motion energy into heat within a robust galvanized steel plate housing. Rated for 3.5 kW Peak Power, this fixed-resistor module incorporates a steel screen design that protects internal windings and ensures uniform thermal distribution. Designed for industrial automation, it supports an Operating Factor of 60 % SD and withstands ambient conditions up to Maximum Operating Temperature of +70 °C. Integrated monitoring points enable real-time verification of ventilation and temperature to maintain consistent braking performance.
This braking resistor features a Resistance at SD 40 % of 47 Ohm, supporting multiple Switch-on Duration (sd) options—6%, 15%, 25%, 40%, 60%—to match varied duty-cycle requirements. The unit accommodates a Power data of frequency converter up to 4 kW and a Minimum Connectable Resistance Value of 30 Ohms, while the Thermal Time Constant (tbw) of 100 seconds defines its heat-soak profile under peak loads. A Circuit Cross-section of 2.5 mm² for standard connection configurations ensures reliable current flow, and the Admissible Operating Humidity rating of maximum 90% non-condensing guarantees resilience in humid environments. External ventilation with Ventilation Requirement for air-current monitoring optimizes cooling, and the entire assembly mounts easily via a wall-mountable assembly option with secure terminals and a perforated cover.
Engineers will value how the RZW02.1-004-060 integrates seamlessly into control panels and drive cabinets, offering straightforward installation and low maintenance. Its IP23 Protection housing and temperature ceiling safeguard against dust ingress and thermal overload, ensuring long-term reliability in industrial settings. This braking resistor enhances drive system stability and energy balance, making it ideal for conveyor lines, packaging machinery, and other applications demanding precise, repeatable deceleration.
