RZW02.1-003-015

The Bosch Rexroth Indramat RZW02.1-003-015 from the RZW Braking Resistors series delivers reliable braking energy dissipation with a converter power rating of 3 kW and a precise resistance of 6.8 Ω. Designed for industrial automation, it handles a peak power of 2.2× continuous power at 40% switch-on duration and maintains performance across relative switch-on durations of 6%, 15%, 25%, 40%, and 60%. The robust unit exhibits a thermal time constant of 100 s and weighs between 1.8–8.8 kg depending on the selected type, providing a balance of durability and compactness. This braking resistor is ideally suited for medium-duty drive systems where controlled energy dissipation is critical.

Engineered with a wire-wound lamella design structure for wall assembly, the RZW02.1-003-015 features a galvanized steel housing sealed with rubber grommets to guard against dust and moisture ingress (IP23). The fixed resistor type with steel-screen housing and external ventilation ensures heat is expelled efficiently during continuous braking operations. Installation guidelines specify minimum installation spacing and adequate operating airflow to optimize thermal management and prevent hotspots. For extended cycles, switch-on cycle times (Ton_max 48 s; Toff 72 s at 40% switch-on duration) guarantee stable operation under repetitive load transients.

In practice, the RZW02.1-003-015 enables precise braking control in motion control architectures by converting excess regenerative energy into heat safely and predictably. Its lamella resistor geometry and ventilated housing minimize thermal stress and extend component life under cyclic loading. Compact, rugged, and compliant with industrial standards, this braking resistor is the cornerstone of reliable energy management in automated drive systems.
