RZW02.1-005-060

The Bosch Rexroth Indramat RZW02.1-005-060 braking resistor from the RZW Braking Resistors series is engineered to deliver high braking power in a compact housing, enabling reliable dissipation of regenerative energy during motor deceleration. Its robust ceramic resistive element is not flammable, providing additional fire protection in industrial settings. Designed for large inertia masses and extended braking procedures, this unit converts excess current into heat, which is efficiently conducted through an aluminum enclosure. Internationally certified and tested by independent laboratories, it features a clear type label with identification data to ensure traceability and compliance. The device supports peak installation altitudes up to 1000 meters above sea level, maintaining stable operation under diverse environmental conditions.

Technical specifications are optimized for industrial automation. The resistor supports Voltage Range of 380-480 V and handles a Nominal Current of 4.5 A with a Rated Power of 5 kW and Power data of 5.5 kW. Thermal performance is governed by a Peak Surface Temperature limit of 80 degrees and a Permissible Ambient Temperature from 2 to 45 degrees. It operates over a Temperature Range of -10°C to +60°C and tolerates mains Frequency of 50/60 Hz. The design employs Natural convection cooling and requires a minimum connectable cable resistance of 30 ohms. An attached Name Plate provides key data, and packaging uses recyclable cardboard for sustainable transport.

Operational features emphasize ease of installation and long-term reliability. The resistor exhibits a power time constant of 100 seconds, matching the braking profile of connected converters with Operating Factor of 0.6. Grounding is critical; a protective earth conductor of at least 10 mm² cross-section must be installed to ensure safe discharge of energy. The housing’s aluminum construction offers exceptional thermal conduction, but operators must maintain ambient temperatures between 0 and 40 °C and eliminate condensation to preserve performance. When in operation, the resistor’s heat dissipation may raise local temperatures, so sensitive components should be positioned at a safe distance.

System integration is seamless with Bosch Rexroth drive controllers, augmenting converter stability and extending service intervals. Multiple RZW resistors can be paralleled according to the installation guidelines provided in the documentation, enhancing braking capacity for large-scale equipment. Worldwide delivery and international certification simplify procurement for global operations in packaging, material handling, and machine tool centers. This braking resistor is ideal for industrial automation applications demanding high dependability, compact footprint, and efficient regenerative energy management.
