JJY023434020003 SIEMENS Exclusive Braking Resistor for PM240-2 Power Module Original Brand New

The SIEMENS JJY023434020003 braking resistor is a high-quality accessory designed for reliable operation with the PM240-2 Power Module, frame size FSG. This unit plays a vital role in industrial drive systems by dissipating excess energy from the DC link. When the Power Module cannot regenerate energy back into the supply grid, the braking resistor ensures stable performance by converting surplus electrical energy into heat. This makes it an essential component for demanding applications where rotational energy from motors must be managed safely and effectively.

Offering a continuous power capacity of 2750 W and a resistance value of 2.5 ohms, the braking resistor is engineered to handle braking operations up to a maximum of 55 kW under defined duty cycles. It supports smooth and efficient operation of PM240-2 Power Modules by preventing overvoltage conditions and safeguarding sensitive electronics. Its robust construction and UL-listed temperature switch provide reliable overheating protection, reducing the risk of damage and prolonging equipment lifespan.

Overview

Designed for lateral installation beside the PM240-2 Power Modules, this resistor enables flexible setup within industrial environments. To minimize heat buildup inside enclosures, Siemens recommends placing the braking resistor outside the control cabinet or switchgear room. This reduces cooling requirements and ensures long-term system efficiency. For frame sizes FSD through FSG, an optional shield connection kit is recommended to guarantee electromagnetic compatibility.

Every resistor is equipped with a temperature switch that can be evaluated by the system to trigger protective actions in case of overheating. This feature enhances operational safety and aligns with international quality standards. The combination of energy dissipation, compact form factor, and Siemens engineering excellence makes this braking resistor a dependable choice for automation systems worldwide.
