Product Description:
The Bosch Rexroth Indramat RZW03.1-075-025 is a part of RZW Braking Resistors used for industrial setups.
Its 75 kW capacity enables this resistor to meet demands in industrial environments that require stable braking at medium levels. This equipment design comes with a resistance level of 4.9 Ω and uses a 25% switch-on period that keeps the unit active for up to 30 seconds per 2-minute operation cycle. The system functions with predetermined on and off periods of a total of 90 seconds to achieve complete cooling between stop events. The device connects effectively to resistances as low as 3.75 Ω, therefore serving various motor control devices and systems that need braking control. At 100 seconds, the thermal time constant helps the unit regulate heat absorption and dispersion effectively to maintain safety during operations. It is best used indoors under supervision because of its IP23-tested galvanized steel frame, which protects against solid objects and water spray.
The RZW03.1-075-025 model measures 490 by 395 by 520 mm with a weight of around 26 kg and fits well into various installation spaces. The system comes with a 4 mm² cross-sectional cable area and uses a wind vane relay monitoring connection for its terminals to track airflow speed and working status of the cooling system. This device works best within a temperature range from 0 to 40 degrees Celsius, which matches most industrial spaces. It can be purchased at Wake Industrial with a one-year warranty.
