RZW03.1-132-025
RZW Braking Resistors
The Bosch Rexroth Indramat RZW03.1-132-025 from the RZW Braking Resistors series combines robust industrial design with precision braking performance. It delivers a 119 kW peak power rating and operates on a minimum connectable resistance of 2.2 Ω, supporting 6%, 15%, 25%, and 40% operating factors for varied duty cycles. Engineered for factory environments, it features a galvanized steel plate housing rated to IP23 protection class and sustains an ambient operating temperature of 0°C to +40°C. The resistor maintains internal stability with a 100 s thermal time constant and a 90% maximum humidity tolerance for non-condensing conditions.
Assembly and mounting are streamlined by its stable floor or panel configuration, while the 132 kW power class rating ensures compatibility with high-demand drive systems. During operation, surface temperatures may reach up to 80°C, yet controlled heat dissipation prevents thermal overload. The unit’s -25°C to +70°C storage temperature range enables secure handling and staging between installations. Integrated thermal protection safeguards the resistor during extended braking intervals, minimizing downtime and maintenance requirements.
Designed for medium-duty industrial usage, the RZW03.1-132-025 braking resistor adapts to numerous SD types, including F3 (2.5 Ω, 50 mm²) for 6%, F9 (2.6 Ω, 70 mm²) for 25%, and F11 (2.3 Ω, 95 mm²) for 40% operating factors. Its configurable weight varies by assembly to meet application-specific inertia loads and space constraints. With its combination of precise power handling, resilient construction, and flexible duty profiles, this resistor is an ideal solution for modern industrial automation braking requirements.
