RZW01.1-110-NNN

The Bosch Rexroth Indramat RZW01.1-110-NNN braking resistor delivers a high-performance solution within the RZW Braking Resistors series, engineered for demanding industrial automation environments. This unit provides a substantial power class of 110 kW rating while maintaining a continuous dissipation capability of 1.6 kW at 100% SD, ensuring reliable braking energy management in high-load applications. By converting excess kinetic energy into heat, the RZW01.1-110-NNN safeguards servo drives and motion control systems against overvoltage conditions. Featuring a robust galvanized steel housing and weighing 26 kg (for F1 Type), it combines mechanical durability with structural stability. Compact yet powerful, this resistor supports prolonged duty cycles without compromising performance.

In terms of technical specifications, the RZW01.1-110-NNN offers a precise resistance of 47.0 Ω and requires a minimum connectable resistance of 2.5 Ω for safe operation. The device supports an adjustable operating factor of 40% to 60% SD, offering a peak-to-continuous power ratio of 2.2 at 40% SD and 1.5 at 60% SD to match diverse braking profiles. Thermal management is quantified by a thermal time constant of 150 s, enabling predictable heat dissipation across repetitive cycles. Braking intervals are defined by a switch-on duration of 48 s followed by a switch-off duration of 72 s within a standardized 120-second load cycle. The resistor maintains IP23 protection class to guard against medium-sized solids and water ingress, ensuring resilience in industrial settings.

Operationally, the RZW01.1-110-NNN is designed for ease of installation and maintenance: the galvanized steel housing provides corrosion resistance, while the specified installation instructions to maintain sufficient spacing ensure adequate ventilation and thermal clearance. The resistor exhibits consistent performance over extended duty cycles, with no degradation in braking efficiency during repeated applications. A one-year warranty covers manufacturing defects, offering end users confidence in long-term reliability. At 26 kg, the F1 Type variant demands professional mounting with room for airflow, but its compact footprint integrates smoothly into existing drive cabinets and control panels.

System integration is streamlined for compatibility with Bosch Rexroth Indramat and third-party servo drive platforms, making the RZW01.1-110-NNN ideal for high-power motion control, servo system braking, and dynamic deceleration tasks. Its standardized electrical connections and robust thermal design suit applications in injection molding, packaging machinery, and material handling systems. By providing a stable braking buffer and predictable thermal behavior, it enhances overall system uptime and safeguards critical components in demanding industrial automation scenarios.
