RZW02.1-015-006

The Bosch Rexroth Indramat RZW02.1-015-006 is a high-performance member of the RZW Braking Resistors family, designed to manage dynamic energy dissipation in industrial drive systems. Manufactured by Bosch Rexroth Indramat, this unit features a robust galvanized steel housing and weighs 18 Kg for secure cabinet installation. Its Power Rating of 15 kW combined with a Resistance Value of 18 Ω ensures reliable braking performance, supported by a Protection Class IP 20 rating for application in controlled environments. The compact Dimensions of 190 mm x 330 mm x 480 mm and standardized mounting pattern allow seamless integration into standard drive cabinets.

Technical excellence is delivered through a carefully specified resistor network and cooling system. The RZW02.1-015-006 employs an axial ventilator with 3.5 kVA capacity to maintain optimal temperatures during operation, while its Thermal Time Constant of 100.0 s provides predictable heat dissipation characteristics. Electrical connections utilize a 10 mm² cross-section (cable) input, facilitating high current throughput with minimal voltage drop. The resistor can be included with a Minimum Connectable Resistance of 17 Ω to tailor braking force, and features multiple Switch-on Durations (sd) of 6%, 15%, 25% for flexible duty cycles. An Operating Factor of 6% at rated power ensures safe duty under intermittent operation.

Operational reliability is enhanced by strict environmental and thermal management criteria. The unit is intended for a Usage Condition of a dust-free environment between 0°C to 40°C, preventing ingress and maintaining insulation integrity. The combination of Material: Galvanized steel housing and IP 20 protection balances structural strength with service accessibility. Continuous braking cycles benefit from balanced resistance and ventilation, avoiding thermal overload even under frequent engagement. The specified Power Class of 15 kW peak capacity addresses medium-duty braking demands in servo drives and motion control systems.

Integration into automation platforms is straightforward, with the resistor series supporting standard cabinet layouts and forced-air cooling schemes. The RZW02.1-015-006 braking resistor is ideally suited for applications in CNC machines, packaging lines, textile machinery, and robotic workcells requiring precise energy recovery and heat rejection. Its dimensional conformity and consistent performance metrics simplify system design and commissioning. Pairing with Bosch Rexroth Indramat drives and controllers unlocks advanced braking algorithms and fault-monitoring features for complete drive system optimization.
