JJY023464020001 SIEMENS Exclusive Braking Resistor for Power Module PM240-2 Original Brand New

JJY023464020001 SIEMENS Exclusive Braking Resistor for Power Module PM240-2 Original Brand New

The SIEMENS JJY023464020001 braking resistor is a reliable and high-quality component engineered for use with PM240-2 Power Modules, frame size FSG. Designed to safely dissipate excess energy in the DC link, this braking resistor ensures stable performance and reliable protection of the drive system during regenerative operation. With a rated resistance of 5 ohms and a continuous power capacity of 5500W, it is ideal for industrial applications requiring precise and consistent energy management.

This resistor is assembled using two JJY023434020001 braking units connected in parallel, delivering enhanced performance for demanding operating conditions. By converting surplus electrical energy into heat, it prevents system overload and contributes to safe and efficient machine operation. It is especially useful in scenarios where rotating masses with high inertia need to be decelerated quickly and securely.

Overview

Specifically designed for PM240-2 Power Modules, the braking resistor serves as an external energy dissipation device when regeneration to the supply network is not possible. During braking operations, the generated energy is absorbed and converted into heat, maintaining the stability of the power module and extending the service life of the overall system. Installation is flexible, as the unit can be placed laterally next to the PM240-2 modules. For frame sizes FSD to FSG, positioning outside the control cabinet or switchgear room is recommended to optimize heat dissipation and minimize cooling requirements.

Design

The braking resistor is equipped with an integrated UL-listed temperature switch. This safety feature helps prevent overheating by triggering an evaluation system to protect equipment from damage. For improved electromagnetic compatibility, an appropriate shield connection kit should be ordered for frame sizes FSD to FSG, ensuring reliable performance in complex industrial environments.
