RZW03.1-022-025

The Bosch Rexroth Indramat RZW03.1-022-025 from the RZW Braking Resistors series is engineered to deliver reliable dynamic braking performance with a power class of 22 kW and a peak power rating of 20 kW. Housed in robust galvanized steel housing and certified to IP23 protection class, this braking resistor ensures secure operation in ventilated industrial environments. Its Weight (type F2) of 36 kg and compact footprint make it straightforward to integrate into existing automation systems without compromising cabinet density. Designed for demanding automation tasks, it offers consistent energy dissipation and system stability under repetitive deceleration cycles.

Featuring a Fixed Resistor Type F design, the RZW03.1-022-025 provides precise control of braking energy through multiple resistance settings: Resistance Sd 6% of 12 Ω, Resistance Sd 15% of 15 Ω, and Resistance Sd 25% of 14 Ω. The corresponding conductor cross-sections—4 mm² at 6% Sd, 6 mm² at 15% Sd, and 10 mm² at 25% Sd—maximize current capacity while minimizing thermal hotspots. A minimum connectable resistance of 11.6 Ω combined with an operating factor Sd of 25% ensures the resistor can handle peak loads without exceeding its thermal time constant of 150 s. These specifications guarantee a stable temperature profile and predictable duty cycles in high-demand braking applications.

Built to industrial-grade standards, the RZW03.1-022-025 excels in applications requiring precise braking control, such as conveyor systems, robotics, and winches. Its galvanized steel enclosure not only resists corrosion but also withstands mechanical vibration and shock, enhancing long-term durability. Certified IP23, this braking resistor safeguards against solid object ingress and light water exposure, making it ideal for ventilated installations where reliable power dissipation is critical.
