JJY023422620001 SIEMENS Exclusive Braking Resistor for PM240-2 Power Module Original Brand New

The SIEMENS JJY023422620001 braking resistor is a high-quality accessory designed for reliable use with PM240-2 Power Modules, frame size FSG. Engineered for performance, it ensures the safe dissipation of excess energy within the DC link during regenerative braking conditions. This component is an essential addition when the connected Power Module cannot feed energy back into the supply system, making it critical for applications involving deceleration of rotating machinery with significant inertia. By converting surplus energy into heat, the resistor provides stability, safety, and protection for the drive system.

Compact yet powerful, the unit is rated at P_MAX = 22 kW over 12 seconds with 5% duty cycle, offering a resistance of 25 ohms and continuous power capacity of 1100 W. The built-in temperature switch, UL-listed for safety, adds an extra layer of protection by monitoring heat levels and preventing damage in case of overheating. This function safeguards not only the braking resistor but also the Power Module and the surrounding equipment.

Overview

Designed specifically for PM240-2 Power Modules, the JJY023422620001 braking resistor is intended to be mounted laterally next to the drive unit. To maintain efficiency and reduce cooling requirements, resistors for frame sizes FSD to FSG are ideally positioned outside of the control cabinet or switchgear room. This placement strategy reduces heat load on the main system, minimizing the need for extensive air conditioning while improving long-term system reliability.

Design

The resistor features a durable construction with integrated safety mechanisms. For electromagnetic compatibility, a dedicated shield connection kit is recommended for frame sizes FSD to FSG. Its rugged design, efficient heat dissipation, and optimized installation flexibility make it an essential accessory for demanding industrial applications requiring frequent braking cycles and consistent performance.
