JJY023464020002 SIEMENS Exclusive Braking Resistor for Power Module PM240-2 FSF Original Brand New

JJY023464020002 SIEMENS Exclusive Braking Resistor for Power Module PM240-2 FSF Original Brand New

The SIEMENS JJY023464020002 braking resistor is a robust and reliable solution designed for use with PM240-2 Power Modules, frame size FSF. With a rated maximum power of 110 kW for short-term operation and continuous dissipation power of 5500 W, this resistor ensures stable and efficient energy handling in demanding industrial environments. It is built using two JJY023434020002 resistors connected in parallel, guaranteeing long-lasting durability and dependable performance under heavy load conditions.

Braking resistors are essential when dealing with regenerative energy that cannot be fed back into the supply system. In applications where rotating machinery or high-inertia equipment needs controlled deceleration, excess energy generated in the DC link is safely dissipated as heat by the braking resistor. This provides both protection and stability for the Power Modules while preventing overvoltage and system downtime.

Overview

The JJY023464020002 is specifically engineered for use with PM240-2 Power Modules equipped with an integrated braking chopper. Designed to be installed laterally next to the module, it ensures easy integration into control cabinets. However, for frame sizes FSD to FSG, it is recommended to mount the resistor outside the cabinet or switchgear room to effectively manage heat dissipation and reduce cooling demands.

Each resistor includes a UL-listed temperature switch, providing an additional safety layer. This feature allows for monitoring and evaluation to prevent overheating and possible damage to connected systems. For optimal electromagnetic compatibility, a shield connection kit is required for frame sizes FSD through FSG. Together, these design features make the JJY023464020002 a reliable component for energy dissipation in industrial drive systems.
