RZW01.1-011-NNN

The Bosch Rexroth Indramat RZW01.1-011-NNN braking resistor is part of the RZW Braking Resistors series, engineered for robust energy dissipation in industrial motion control applications. This fixed resistor with steel screen design offers a resistance of 20 Ω and provides a continuous power loss rating of 0.18 kW with peak capability of 32 kW for 1 second. It is enclosed in a galvanized steel plate housing featuring an IP23 protection class, complemented by a steel screen for enhanced thermal exchange. The device supports horizontal installation of terminals on galvanic plate resistance protectors as specified under its Admissible Assembly Conditions, ensuring straightforward integration. With a fully encapsulated Enclosure and a lightweight Weight of 2.3 kg, the RZW01.1-011-NNN simplifies both mounting and maintenance operations.

The thermal management characteristics of the RZW01.1-011-NNN ensure consistent performance under varying duty cycles. It employs a Calculated Thermal Time Constant of 100 s and adheres to the Braking Power Validity curve across switch-on durations of 6%, 15%, 25%, 40%, and 60% over a 120 s load cycle. The Thermal Capacity Calculation Formula is valid for nominal switching, allowing precise thermal design and system-level coordination. Constructed from a durable metal alloy with ceramic insulation and protected by an Enclosure rated IP23, the resistor withstands housing temperatures up to 80 °C and ambient ranges from 0 to 40 °C. A Line Cross Section of 2.5 mm² ensures reliable current distribution, while the Mounting Style supports external panel integration without compromising service access.

Designed for harsh industrial automation environments, the RZW01.1-011-NNN offers high reliability and straightforward connectivity. Two main terminals (X1.C and X1.F) facilitate converter linkage, with a recommended copper ground of at least 10 mm², and Protection (Connection Terminals) rated IP10 to guard against dust ingress. Its robust construction and encapsulation deliver stable long-term performance, even under repetitive deceleration braking cycles. This braking resistor integrates seamlessly into drive systems for packaging machinery, CNC machining centers, and conveyor applications, providing precise energy control and enhanced system safety. The combination of a galvanized housing, comprehensive protection ratings, and measured thermal response makes the RZW01.1-011-NNN an essential component for optimized motion control solutions.
