Product Description:
The RZW02.1-037-025 Braking resistor series from Bosch Indramat offers an effective solution for energy dissipation in industrial automation systems. With an IP20 rating, this RZW series is built to deliver dependable braking performance. Bosch Indramat ensures that the RZW02.1 series satisfies the power and resistance standards for different kinds of brake uses.
The minimal connectable resistance of the RZW02.1-037-025 brake resistor is 7 ohms, and it has a peak power rating of 33 kW for one second. With a thermal time constant of 100 seconds, the resistor utilizes a steel screen type B/C resistor. A bolt-on installation perpendicular to the assembly surface is the recommended method of mounting the braking resistor. A porcelain termination box with PG screw terminals ensures solid electrical connections for the brake resistor. There is sufficient heat dissipation due to the perforated steel housing. With a 25 mm²cable cross-section and a resistance of 7.3 ohms, the switching duty is categorized as B3. The 25% switching duty cycle that the resistor can handle allows it to run for 30 seconds on and 90 seconds off. A combination of a perforated enclosure and a steel screen resistor type maximizes thermal performance.
The function of the RZW02.1-037-025 brake resistor is to provide reliable operation and effective control of heat. When applying brief bursts of braking force, its thermal time constant keeps it from overheating. The interior components are protected against solid objects larger than 12.5 mm by the IP20 protection rating. The resistor's terminal design and mounting make it straightforward to install and maintain. We guarantee compatibility with a range of braking system configurations, with the switching duty and resistance levels. To control the amount of force applied when stopping an automated system, this braking resistor is an excellent option.
