RZW03.1-200-006

The Bosch Rexroth Indramat RZW03.1-200-006 from the RZW Braking Resistors series combines industrial-grade braking performance with robust design characteristics and precise electrical control. It offers a resistance of 1.8 Ω optimized for 200 kW frequency converter power applications and withstands peak power absorption up to 180 kW during deceleration events. Housed in a galvanized steel enclosure with a Protection Rating of IP 23, the unit is engineered to resist dust ingress and water spray for reliable operation in industrial automation environments. The design delivers accurate dissipation of regenerative energy while maintaining stable thermal behavior for consistent drive performance.

Thermal management is highlighted by a thermal time constant of 100 s, enabling controlled heat dissipation under varying load profiles. Ambient operating conditions span 0 ... 40 °C, while storage ranges from -25 °C to +70 °C, ensuring resilience across diverse climates. The braking resistor tolerates relative humidity up to 90 % (noncondensing) without performance degradation, and heavy-duty connections are facilitated by 70 mm² cross-section terminals that minimize hotspot formation. A minimum connectable resistance value of 1.6 W ensures compatibility with high-power drives and maintains system stability during repeated braking cycles.

The compact footprint measures 595 x 490 x 770 mm and a weight of 61 kg simplifies panel integration and supports high-density cabinet layouts. With galvanized steel housing, IP 23 protection, and precise electrical characteristics, the RZW03.1-200-006 braking resistor is engineered for dependable energy management in demanding motion control and automation applications. Its combination of robust construction and defined technical specifications makes it an ideal solution for modern industrial drive systems.
