JJY023423320001 SIEMENS Exclusive Braking Resistor for PM240-2 Power Module Original Brand New

The SIEMENS JJY023423320001 Braking Resistor is designed for use with PM240-2 Power Modules and provides a reliable solution for dissipating excess energy generated during braking operations. With a rated resistance of 4.5 ohms and a continuous power dissipation capacity of 1500W, this component ensures safe and stable operation even under demanding industrial conditions. Its peak handling capacity reaches 30kW for short durations, making it suitable for applications where sudden deceleration or high rotational inertia is involved.

By converting surplus energy into heat, the braking resistor prevents potential overloads in the DC link. This makes it an essential accessory for power modules that include an integrated braking chopper but are not capable of regenerative feedback to the supply system. The compact yet durable design enables installation laterally beside PM240-2 units, ensuring easy integration into existing systems while maintaining efficient thermal management.

Overview

The braking resistor is purpose-built for PM240-2 Power Modules, frame size FSG, and plays a critical role in energy dissipation during regenerative braking scenarios. To maximize safety, each unit is equipped with a UL-listed temperature switch, which should be evaluated in the control system to avoid damage in the event of overheating. This added layer of protection enhances operational reliability and extends the lifespan of the connected drive components.

For optimal performance, it is recommended to install the resistor outside the cabinet or switchgear room to reduce excess heat within the control environment. This approach minimizes air conditioning requirements and ensures more efficient energy management. For EMC-compliant installation, a shield connection kit is available for frame sizes FSD to FSG, further simplifying integration into industrial environments.
