JJY023434020002 SIEMENS Exclusive Braking Resistor for Power Module PM240-2 Original Brand New

The SIEMENS JJY023434020002 braking resistor is a robust and reliable component designed for use with PM240-2 Power Modules, frame size FSG. This high-performance resistor plays a crucial role in industrial drive systems by dissipating excess energy generated in the DC link. During deceleration or regenerative operation, large amounts of energy can be produced, especially when braking rotating equipment with high inertia. Since the PM240-2 Power Modules cannot feed this energy back into the supply network, the braking resistor ensures safe energy conversion into heat, protecting the drive and enhancing system stability.

Rated at P_MAX=55kW/12s/5% ED with a resistance of 21 Ohm and a continuous dissipation power of 2750W, this braking resistor is engineered for demanding applications. Its durability and efficiency make it a dependable solution for long-term use in industrial automation and motor control environments where controlled braking is essential.

Overview

The JJY023434020002 braking resistor can be mounted laterally next to PM240-2 Power Modules. For larger frame sizes (FSD to FSG), installation outside the control cabinet is recommended to allow better heat dissipation and to minimize cooling requirements within switchgear rooms. Every resistor is equipped with a UL-listed temperature switch that safeguards against overheating and prevents potential system damage by monitoring thermal conditions.

For optimal electromagnetic compatibility, a shield connection kit should be ordered when connecting the braking resistor to frame sizes FSD to FSG. This ensures compliance with industrial EMC standards and guarantees stable operation in challenging environments.
