RZW02.1-037-015
RZW Braking Resistors
The Bosch Rexroth Indramat RZW02.1-037-015 braking resistor from the RZW Braking Resistors series combines a power class of 37 kW with a rated power of 33 kW in a robust industrial design. It delivers a peak power at 15% SD of 33 kW and features a minimum connectable resistance of 7.4 Ω to ensure precise management of regenerative energy during motor deceleration. Certified to IP 23 protection class, the unit withstands dust and moisture ingress in factory environments while safeguarding internal components. Designed for seamless integration with frequency converters and drive modules up to 37 kW, this resistor ensures stable braking performance in demanding automated applications.
Constructed from heavy-gauge galvanized steel housing that complies with VDE0298 regulations, the RZW02.1-037-015 resists corrosion and mechanical stress on production floors. The recommended cross-section for connection of 10 mm² (AWG 10) and grounding conductor sizing ensure safe power routing and reliable earthing. With an operating factor of 15% SD, the resistor supports a maximum switch-on time of 48 s followed by a required off-time of 72 s, leveraging its thermal time constant of 100 s for rapid heat dissipation between cycles. Weighing 15 kg and offering standardized mounting points, it allows for both horizontal and vertical cabinet installation with minimal footprint.
To maintain optimal performance, follow the additional guideline to ensure free airflow and ambient temperatures below 40 °C around the resistor housing. Integrated monitoring of temperature and duty cycle within compatible drive firmware enables protective derating to extend component lifespan. The RZW02.1-037-015 is an essential element for energy-efficient braking and regenerative energy management in complex industrial automation systems.
