RZW02.1-037-060

The Bosch Rexroth Indramat RZW02.1-037-060 braking resistor is part of the renowned RZW Braking Resistors series, engineered to provide superior braking performance in industrial automation applications. This fixed resistor boasts a continuous power rating of 22.5 kW and a peak power capability of 33 kW, ensuring reliable energy dissipation during high-demand deceleration cycles. With a nominal resistance of 7 Ohms and a power class of 37 kW, it is specifically designed to absorb regenerative braking energy from frequency converters, protecting drive components and maintaining process stability.

Incorporating a robust galvanized steel housing, the RZW02.1-037-060 offers an IP20 protection class against solid contaminants, while its optimized finned design and high thermal conductivity materials maximize heat dissipation. The unit measures Width: 686 mm, Height: 120 mm, with a compact form factor suitable for enclosed cabinet installations. Its thermal time constant of 100 s and safety temperature limit of 80 °C guarantee predictable thermal behavior under continuous operation, and the resistor supports an operating factor of 60% SD for intermittent duty cycles. Switch-off and switch-on times are defined at 48 s max and 72 s max, respectively, enabling precise control of energy dissipation logic in automated systems.

Compatibility with standard industrial drive architectures makes the RZW02.1-037-060 highly versatile. The resistor’s minimum connectable resistance of 7 Ohms and rigid mounting requirements ensure secure installation on stable surfaces, while its fixed configuration eliminates movable parts and enhances durability under pulse load conditions. Although no specific certification standards are listed, the IP20 rating and galvanized enclosure material inherently meet industry expectations for mechanical protection and corrosion resistance. By integrating this braking resistor into motor drive circuits, engineers can achieve efficient regenerative energy management, reduce braking distances, and prolong the lifespan of drive components, ultimately improving overall system performance and reliability in demanding industrial environments.
