B84143C1250S250

Power Line Filter Modules Overview

The B84143C1250S250 is a three-phase power line filter module manufactured by TDK EPCOS, designed for high-current converter applications. It features a rated current of 1250 A and supports rated voltages of 305/530 V AC at 50/60 Hz. The unit utilizes an IP00 housing suitable for chassis mounting. It achieves a short-circuit current rating (SCCR) of 100 kA to meet UL standards for switchgear structures. The filter provides superior attenuation characteristics in the 9 kHz to 150 kHz frequency range. Ground leakage current is specified at 46 mA, complying with IEC 60939-1:2010. Certifications include IEC 60939-3, UL 60939-3, and CSA C22.2 No. 8.

Power Line Filter Modules Procurement Notes

Verify that the specific S250 voltage variant matches the 305/530 V AC requirement for your application. Confirm that the chassis mounting configuration aligns with your enclosure design. Ensure the 1250 A current rating exceeds peak load demands. Check that the IP00 housing allows for adequate cooling and protection in the installation environment. Validate certification requirements against local regulatory standards.

Power Line Filter Modules Selection Notes

Select this model when high current capacity above 1000 A is required for three-phase systems. Consider the S250 voltage rating if operating at 305/530 V AC. Evaluate the physical dimensions against available space, as larger current ratings result in increased footprint. Assess the need for high SCCR values in fault-prone environments. Compare attenuation needs against standard filters if frequencies below 9 kHz are primary concerns.

Power Line Filter Modules Part Context

This component belongs to the B84143C series of three-line filters for converters and power electronics. The series offers various rated currents from 160 A to 2500 A. Different suffixes indicate voltage ratings, such as S250 for 305/530 V AC and S251 for 440/760 V AC. The series is engineered for industrial power electronics with emphasis on compactness and high reliability.

Power Line Filter Modules Replacement Considerations

Direct substitutes within the same series include other B84143C models with different current ratings but identical voltage and mounting configurations. Verify that any replacement maintains the 100 kA SCCR and IP00 rating. Cross-reference the physical dimensions to ensure fitment. Confirm that the alternative part holds the same UL, CSA, and IEC certifications.
