RZW02.1-075-040

The Bosch Rexroth Indramat RZW02.1-075-040 braking resistor from the RZW Braking Resistors series delivers a robust solution for industrial deceleration and energy dissipation, offering 67 kW peak power capacity with a 24V DC power supply. Designed for precision braking applications, this resistor ensures controlled deceleration of motors by converting kinetic energy into heat via passive dissipation. Its compact footprint of 50x50x25 mm allows simple integration into existing control cabinets or panels without extensive redesign. The lightweight construction at 120 g facilitates easy handling and installation while preserving structural integrity. With Type C2 specification, the RZW02.1-075-040 meets stringent industrial automation requirements for safety and performance.

Detailed technical specifications underscore the resistor’s suitability for demanding environments. The device features screw terminal connections with a 50 mm^2 cross-section for reliable electrical interfacing and low-resistance contact. Its nominal resistance of 5.4 Ω and a minimum connectable resistance of 3.75 Ω accommodate a variety of braking curve profiles. The resistor operates at a current consumption of 0.8A, ensuring minimal draw under steady load conditions. The housing is constructed from an aluminum heat sink with an insulated mounting base, optimizing thermal transfer and mechanical protection. An operating factor of 40% SD defines continuous duty limits, enabling predictable performance under cyclic loads.

Operational features emphasize long-term reliability and safety. The RZW02.1-075-040 supports overload protection through thermal dissipation, preventing component failure during peak braking events. Its specified operating temperature range of –10°C to +60°C allows deployment in varied ambient conditions without derating. Mounting flexibility is provided via a standardized panel or control cabinet mount, ensuring secure fixation and adequate airflow for heat rejection. Passive cooling through the integrated heat sink eliminates the need for auxiliary fans, reducing maintenance points and potential contamination. The resistor’s compact design and consistent thermal profile sustain performance over repeated braking cycles.

Integration of the RZW02.1-075-040 into industrial automation systems is streamlined through its universal mounting options and standard electrical interface. Compatible with drive controllers and PLC-based safety circuits, it enhances system-level overload prevention without bespoke hardware modifications. Target applications include CNC machining centers, automated gantry systems, material handling conveyors, and robotic workcells where controlled energy dissipation is critical. Bosch Rexroth Indramat’s proven design and rigorous quality controls ensure that the RZW02.1-075-040 meets the reliability demands of modern industrial operations.
