Product Description:
The RZW02.1-007-025 Braking Resistor is designed for safe and efficient energy dissipation. It supports high peak power handling and operates with 25 % duty cycle efficiency. The braking resistor is ideal for industrial braking applications requiring thermal stability and consistent performance.
The RZW02.1-007-025 braking resistor by Bosch has a peak power rating of 6.5 kW supported by a power ratio of 3.2 between peak and continuous operation. It operates with a 25 % duty cycle that means it can be active for 30 seconds during each cycle. After this, it requires a minimum OFF time of 90 seconds to cool. The thermal time constant is 100 minutes that indicates how long it takes the resistor to reach thermal equilibrium. It features a resistance value of 33 ohms and a minimum connectable resistance of 30 ohms. The device is a fixed resistor with a steel screen design to provide durability and structural support. Depending on the required connection, it includes either two screw terminals or two M6/M8 stud terminals for secure wiring. Its compact design fits within dimensions of 490 mm (W) x 300 mm (D) x 270 mm (H), making it easy to integrate into control cabinets or equipment enclosures.
The operating temperature range for this The RZW02.1-007-025 braking resistor is between 0 °C and 40 °C. It should not be used in environments with relative humidity above 90 % and humidity must remain non condensing. For safe storage, it should be kept in clean dry areas within a temperature range of – 25 °C to + 70 °C. The RZW series braking resistor weighs 10 kg which contributes to its stability during operation.
Frequently Asked Questions about RZW02.1-007-025:
Q: Can the RZW02.1-007-025 braking resistor handle repeated high-power loads in short bursts?
A: Yes, it supports a peak power of 6.5 kW with a power ratio of 3.2. It runs on a 25 percent duty cycle enabling 30 seconds ON and 90 seconds OFF.
Q: Is the thermal management of RZW02.1-007-025 braking resistor stable for industrial usage?
