JJY:023146720008  JJY023146720008 SIEMENS Exclusive Braking Resistor for Power Module Original Brand New

The SIEMENS JJY:023146720008 braking resistor is a high-quality accessory designed for use with PM240-2 Power Modules, frame size FSG. This durable unit plays an essential role in energy management by dissipating excess energy generated in the DC link during braking operations. While PM240-2 modules feature an integrated braking chopper, they cannot feed energy back into the supply system. Instead, this resistor ensures safe and efficient conversion of braking energy into heat, preventing damage to equipment and ensuring system stability during demanding industrial applications.

This braking resistor is engineered for scenarios such as decelerating rotating masses with high inertia, where regenerative braking would otherwise overload the system. By reliably converting the surplus energy into thermal output, it maintains optimal operation of the connected drive system. Each unit is equipped with a UL-listed temperature switch, which adds an additional layer of protection by providing early warnings in the event of overheating. This ensures operational safety and minimizes the risk of consequential damage, delivering peace of mind to operators and system integrators.

Overview

The JJY:023146720008 module can be installed laterally next to PM240-2 Power Modules, but for frame sizes FSD to FSG, installation outside the control cabinet or switchgear room is recommended. This setup allows the heat generated during operation to dissipate effectively, thereby reducing the air conditioning load inside control cabinets. Additionally, electromagnetic compatibility can be improved by ordering the appropriate shield connection kit, which ensures reliable and interference-free performance.
