JJY023424020002 SIEMENS Exclusive Braking Resistor for PM240-2 Power Module Original Brand New

The SIEMENS JJY023424020002 braking resistor is a high-quality industrial component designed to complement PM240-2 Power Modules. Its primary function is to safely dissipate excess energy from the DC link during braking operations. By converting surplus electrical energy into heat, this braking resistor ensures that power modules function efficiently without overloading the supply system. It is specifically intended for applications where regenerative energy cannot be fed back into the grid, such as braking heavy rotating machinery with high inertia.

Engineered for reliability and safety, the JJY023424020002 braking resistor provides stable resistance values of 31 ohms and supports a continuous power rating of 1850W, with peak power handling of up to 37 kW for short-duration braking events. Each unit is equipped with a UL-listed temperature switch that acts as a safety mechanism to prevent overheating, thereby safeguarding both the resistor and the power module. This makes it suitable for demanding industrial automation environments where uptime and equipment protection are critical.

Overview

The braking resistor is optimized for installation alongside PM240-2 Power Modules, frame size FSG. To maximize heat dissipation and reduce cooling demands inside the control cabinet, the resistor should be installed outside the switchgear room whenever possible. This placement minimizes the strain on air conditioning systems and improves the overall efficiency of the installation. Additionally, the use of an appropriate shield connection kit is recommended to ensure electromagnetic compatibility when connecting the resistor.

With its robust construction, precise design, and focus on safety, the JJY023424020002 braking resistor is an essential accessory for industries relying on PM240-2 Power Modules. It provides an effective and reliable method for managing excess energy, thereby extending the lifespan and stability of the overall drive system.
