6RY1803-0AA00-0AA1 C98043-A7100-L3 Siemens Frequency Converter Equipment 32MB
The Siemens 6RY1803-0AA00-0AA1 (also referenced as C98043-A7100-L3) is a high-quality DC-link choke engineered for use in Siemens SINAMICS modular drive systems, including the SINAMICS S120, S150, and other advanced motion control platforms. With an inductance of 3 mH and a rated continuous current of 250 A DC, this component plays a vital role in stabilizing the DC bus voltage, reducing current ripple, and enhancing the overall reliability and efficiency of multi-axis or regenerative drive architectures.
Installed in the DC link between the line converter (e.g., Active Line Module) and motor modules, this choke limits the rate of current rise (di/dt), suppresses electrical noise, and protects sensitive power electronics—such as IGBTs and DC bus capacitors—from stress caused by rapid load changes or regenerated energy. Its robust, air-cooled design ensures long service life in demanding industrial environments like metal forming, cranes, test benches, printing machinery, and large-scale automation systems.
As an official Siemens component, the 6RY1803-0AA00-0AA1 is fully supported in Siemens engineering tools like SIZER and STARTER, and complies with global safety and environmental standards, ensuring seamless integration into certified drive solutions.
