RZW02.1-045-060

The Bosch Rexroth Indramat RZW02.1-045-060 from the RZW Braking Resistors series delivers reliable energy dissipation with a power rating of 45 kW and a resistance value of 6 Ohm in a compact 710 x 395 x 490 mm footprint. Housed in galvanized steel, this resistor meets IP20 protection class standards and weighs just 37 kg, facilitating installation in industrial automation cabinets. Designed for precision braking, it maintains consistent performance thanks to a thermal time constant of 100 s, which limits thermal drift during high cycling demands. Its minimum connectable resistance of 6 Ohm combines with robust construction to ensure precise deceleration across diverse motion control applications.

Engineered for heavy-duty duty cycles, the RZW02.1-045-060 supports an operating factor (switch-on duty) of 60%, allowing sustained power handling without derating. A peak power of 40 kW capacity provides headroom for transient regenerative currents, while the nominal cross-section of connection at 16 mm² ensures secure high-current terminations. Continuous dissipation is enhanced by a ventilation requirement of unimpeded airflow with filtered air, reducing the risk of thermal overload and extending service life. With rigorous adherence to design stage requirements, it integrates seamlessly into drives and PLC-controlled systems.

Ideal for packaging lines, indexing tables, and high-speed gantries, this braking resistor combines a sturdy galvanized steel housing with low-maintenance operation. Its balance of high power rating, controlled resistance value, and elevated peak power capability makes it indispensable for automation engineers demanding precise, repeatable stopping performance. The RZW02.1-045-060 stands as a cornerstone component in modern industrial automation, offering both reliability and efficiency where rapid energy absorption is essential.
