Product Description:

The Bosch Rexroth Indramat RZW03.1-160-015 provides reliable braking resistor technology for industrial applications.

The RZW series design allows this model to function at 160 kW of power while operating at 400 V. It offers changing resistance levels at different switch-on durations with 2.4 Ω at 6% and 4.4/4.8 Ω in parallel for 15% and 25% sd. Each group of brake resistors has a minimum usable connection of 2.2 ohms to work well with different drive systems. The RZW03.1-160-015 can handle sudden high-energy braking thanks to its peak power capability of 288 kW and thermal time constant of 150 seconds. The device operates under 15% load conditions, naturally dissipating heat through airflow, which makes it suitable for systems that require minimal maintenance. When used appropriately in protected interior spaces, this resistor's IP23-rated housing protects against modest amounts of water infiltration as well as solid objects. Its two mounting options allow users to position this device both vertically and horizontally for optimum use in any setting.

The device functions normally even at temperatures reaching up to 40 degrees Celsius without experiencing any speed reduction. Weight varies according to each chassis setup since this product range works with different types of system sizes. The RZW03.1-160-015 dynamic braking system combines thermal protection and electrical security within a single device, offering a wide range of installation options. The product model offers all needed components and operational dependability for today's motion control systems to work better and handle regenerative energy correctly. It can be purchased at Wake Industrial with a one-year warranty.
