B84143C2500S251

Power Line Filter Modules Overview

The EPCOS B84143C2500S251 is a three-phase power line EMC filter designed for high-current converter applications. It features a rated current of 2,500 A and operates at a rated voltage of 760/440 V AC (50/60 Hz). The unit provides a withstand voltage of DC 3,190 V between line and case for 2 seconds. It is engineered to deliver superior attenuation in the 9 kHz to 150 kHz frequency range and includes a short-circuit current rating (SCCR) of 100 kA to meet UL standards.

Power Line Filter Modules Feature Summary

• Provides high attenuation performance specifically within the 9 kHz to 150 kHz frequency spectrum.
• Engineered with a robust design supporting a short-circuit current rating of up to 100 kA.
• Constructed with an IP00 housing suitable for integration into switchgear structures.

Power Line Filter Modules Applications

• Motor-driven variable frequency drives
• Wind turbines
• Power supply systems

Power Line Filter Modules Procurement Notes

Verify that the specific S251 suffix corresponds to the required 440/760 V AC voltage rating for your application. Confirm physical dimensions and terminal types match the installation space. Ensure the 100 kA SCCR capability aligns with the system's fault current requirements. Check for necessary certifications such as IEC 60939-3, UL 60939-3, and CSA C22.2 No.8 compliance before finalizing procurement.

Power Line Filter Modules Selection Notes

Select this component when high current handling up to 2,500 A is required alongside strict EMI suppression in the 9–150 kHz band. The S251 variant is appropriate for systems operating at 440/760 V AC. Consider the compact footprint relative to its capacity and the need for IP00 protection if housed externally. Evaluate thermal management needs given the high current throughput.

Power Line Filter Modules Part Context

This model belongs to the B84143C series of three-phase EMC filters from TDK/EPCOS. The series targets industrial power electronics and converter applications requiring significant current capacity. The B84143C lineup offers various current ratings from 160 A to 2,500 A, with different voltage variants designated by suffixes like S250 or S251.

Power Line Filter Modules Replacement Considerations

Consult official TDK documentation for direct cross-references. Verify that any substitute maintains the 2,500 A rating, 760/440 V AC specification, and 100 kA SCCR requirement. Ensure identical mounting configurations and terminal styles to avoid mechanical redesign.
