RZW02.1-160-015

The Bosch Rexroth Indramat RZW02.1-160-015 braking resistor is a robust member of the RZW Braking Resistors series designed to safeguard high-inertia drives by converting kinetic energy into heat during deceleration. Featuring a robust 144 kW peak power dissipation capability and a 2.2 Ω minimum connectable resistance, it ensures rapid energy absorption and prevents overvoltage in demanding industrial automation systems. The resistor’s primary function is to protect drive electronics and mechanical components by efficiently managing transient energy during frequent or high-torque braking cycles.

In terms of detailed technical specifications, the RZW02.1-160-015 is rated for a 160 kW power class and supports duty cycles of 40% and 60% SD at a nominal resistance of 4.8 Ω. Its 100 s thermal time constant reflects the time required to reach 63.2% of its temperature rise under continuous load, providing insight into its heating and cooling profiles. This parameter is crucial for system designers evaluating thermal balance in cyclic braking applications. The resistor housing is constructed from Steel for enhanced mechanical stability and passive heat dissipation, while the internal resistive element is engineered to withstand repeated high-power spikes without degradation.

Additional features include selectable protection classes of IP20 or IP23, offering tailored resistance to dust ingress and water spray, suitable for various industrial environments. The sturdy steel enclosure also guards against shock, vibration and corrosive atmospheres, ensuring reliability over extended service life. With a proven ability to handle peak braking loads and a predictable thermal response, the RZW02.1-160-015 enhances system uptime and reduces maintenance intervals. Its integration into industrial drive systems delivers consistent performance, elevated safety margins and overall efficiency gains in automated manufacturing, robotics and material handling applications.
