Product Description:
The RZW02.1-003-040 from Bosch Rexroth Indramat is a part of the RZW Braking Resistors and supports regenerative energy management in drive systems.
Its 3 kW power class rating makes the brake resistor suitable for applications that deal with low to medium power while managing this energy safely to protect the overall system. The RZW02.1-003-040 response mode of 40% switch duration (SD) enables its use in 120-second duty cycles by activating the resistance for no longer than 48 seconds in each cycle. This product emits 3.5 kilowatts of power peaks while holding 100-second thermal times across its surface to dissipate heat and operate reliably during frequent high-load periods. This resistor works with resistances down to 2.5 ohms, making it compatible with different power distribution requirements of industrial systems. Using a wire-wound pipe resistor technology inside a strong galvanized steel enclosure improves both heat venting and mechanical durability. The materials used in construction protect against mechanical stress and promote effective thermal dispersal.
This resistor can be installed in dry, clean locations because it meets IP20 requirements by resisting solid objects measuring over 12 mm. All terminal connections use porcelain parts fastened by PG screws which deliver reliable heat-resistant connections. The resistor operates most effectively within temperature ranges from 0°C to 40°C of ambient conditions, yet it can safely stay within storage temperatures between -25°C and +70°C. The braking resistor offers dependable braking in smaller motor systems thanks to its strong design and good thermal management. It can be purchased at Wake Industrial with a one-year warranty.
