Product Description:
The Bosch Rexroth manufactures the RZW03.1-132-025 braking resistor. It is a part of the RZW Braking Resistors series. The resistor weighs approximately 101 kg which is suitable for stable floor and panel mounting.
The RZW03.1-132-025 braking resistor has a peak power capacity of 119 kW. It is rated for a power class of 132 kW. The resistor housing is made of galvanized steel plate for durability and corrosion resistance which protects internal elements from environmental and mechanical wear. Its protection class is IP23 which allows limited ingress protection from solid objects and water spray. The resistor ambient operating temperature range is 0°C to 40°C which ensures safe operation in moderate environments. Its minimum connectable resistance is 2.2 ohms which allows compatibility with multiple braking units and industrial drive systems. The RZW03.1-132-025 braking resistor support high power loads with thermal protection and long duty cycles. Its storage temperature should be between -25°C and +70°C. The resistor maximum relative humidity is 90 percent in non condensing conditions. It includes a thermal time constant of 100 seconds for controlled heat dissipation. The resistor provides high thermal efficiency and structured design for reliable performance. Its mounting dimensions are 970 mm width and 380 mm depth. The resistor has multiple resistance variants are provided for different operating factors. It operates at a 25 percent duty cycle the F9 type is used with 2.6 ohm resistance and a 70 mm² cable cross section.
The RZW03.1-132-025 braking resistor is built for medium duty industrial usage. It supports a 25 percent operating factor for frequent braking cycles. The resistor surface temperature during operation can reach up to 80°C. It ensures controlled thermal management and load resistance.
