Backorder available · Factory lead time 2–3 weeks.
The SIEMENS JJY023422620002 braking resistor is a high-quality industrial component designed specifically for use with PM240-2 Power Modules. With a rated power of 18.5 kW and a resistance of 7.5 ohms, it ensures efficient dissipation of excess energy generated during braking processes. This reliable accessory is essential when a drive system cannot return regenerative energy back into the supply system. Instead, the braking resistor converts excess electrical energy into heat, protecting the system and maintaining stable performance in demanding applications.
Engineered for heavy-duty use, this braking resistor offers a continuous power dissipation capacity of 930 W. Its rugged construction and reliable thermal management make it suitable for long-term industrial operation. The inclusion of a UL-listed temperature switch provides an added layer of safety, ensuring that overheating is detected and prevented to avoid potential damage to connected equipment. By safeguarding drive components, this resistor contributes to a more efficient and durable automation environment.
The JJY023422620002 braking resistor is designed to work seamlessly with PM240-2 Power Modules that include integrated braking choppers. These modules, while capable of handling transient braking loads, cannot regenerate energy back into the power supply. The resistor effectively manages this by dissipating the surplus energy, particularly useful during the braking of high-inertia rotating machinery. Installation is possible laterally next to the PM240-2 Power Modules, and for frame sizes FSD to FSG, placement outside the control cabinet is recommended. This approach reduces internal heat build-up and minimizes air conditioning requirements, leading to lower operating costs.
Additionally, SIEMENS advises using an appropriate shield connection kit for electromagnetic compatibility when connecting braking resistors to larger frame sizes. This ensures stable performance, compliance with industrial standards, and extended equipment life. Built for reliability, safety, and performance, this braking resistor represents an excellent solution for industrial motion control systems.
