B84143C 250S251

Power Line Filter Modules Overview

The B84143C 250S251 is a three-phase EMC line filter from the EPCOS B84143C series, designed for high-current converter applications. It features a chassis-mount configuration with terminal post connections. The S250 variant supports rated voltages of 305 VAC (L-PE) and 530 VAC (L-L), while the S251 variant supports 440 VAC (L-PE) and 760 VAC (L-L), both at 50/60 Hz. The component handles a rated current of 250 A and offers a short-circuit current rating (SCCR) of 100 kA. It provides superior attenuation in the 9 kHz to 150 kHz frequency range.

Power Line Filter Modules Procurement Notes

Verify the specific suffix code against the manufacturer's datasheet to confirm voltage ratings and physical dimensions. Ensure the installation environment meets the IP00 protection requirements. Confirm that the mounting structure can withstand the specified 100 kA short-circuit current rating during fault conditions.

Power Line Filter Modules Selection Notes

Select this model for applications requiring high current handling up to 250 A. Choose the S250 type for lower voltage systems (up to 530 VAC L-L) and the S251 type for higher voltage systems (up to 760 VAC L-L). Consider the compact footprint if space constraints exist within the switchgear assembly.
