RZW02.1-011-060

The RZW02.1-011-060 braking resistor from Bosch Rexroth Indramat is a robust energy management component in the RZW Braking Resistors series designed for high-performance industrial applications. It features a Peak Power rating of 10 kW and delivers a Resistance (Ω) – SD 40% of 22 Ohm to absorb regenerative energy during deceleration. Constructed with a Housing Material of galvanized steel, the unit ensures mechanical durability and corrosion resistance. With a protection level of IP20 and equipped with 2 screw terminals, M6 connection interfaces, the resistor guarantees secure electrical connections within control cabinets. Its compact footprint and rugged design make the RZW02.1-011-060 ideal for integration in demanding drive systems.

Technically, the resistor falls under Power Class 011 and is classified as type B3 in the design hierarchy, ensuring compatibility with standardized mounting systems. It supports a Resistance (Ω) – SD 60% of 23 Ohom when operating at higher duty cycles and maintains a reliable Thermal Time Constant (s) of 100 seconds for efficient heat dissipation. The device requires a Wiring Cross-section Requirement of at least 10 mm² for the grounded conductor to minimize voltage drop under load. Cable sizing is further defined by a Cross-section (mm²) – SD 40% of 4 and a Cross-section (mm²) – SD 60% of 6 to support continuous current flow without overheating. Each parameter is optimized for precise thermal and electrical load control in automated braking circuits.

In operation, the resistor sustains an Operating Factor of 60% SD, enabling frequent braking cycles without compromising performance, and supports a Minimum Connectable Resistance Value (W) of 20 to limit overload conditions in the system. The galvanized steel housing and IP20 protection class safeguard internal resistor elements, maintaining stable thermal management under peak energy surges. M6 screw terminals simplify installation and provide vibration-resistant clamping, ensuring long-term reliability in harsh industrial environments. Together, these operational features contribute to consistent deceleration control, reduced wear on mechanical brakes, and enhanced system uptime in automated processes.

Integration is straightforward in motor drive cabinets and power conversion panels, supporting industrial automation and machine control applications across packaging, material handling, and robotics. Its compact B3 format and standardized mounting provisions enable plug-and-play replacement or expansion in existing installations. Engineers can leverage the resistor’s precise energy dissipation characteristics to optimize braking profiles and improve overall energy efficiency. The RZW02.1-011-060 is a versatile solution for applications demanding reliable braking energy management and seamless integration into Bosch Rexroth Indramat drive ecosystems.
