Power Line Filter Modules Procurement Notes

Verify the specific part number FMBC-R91R-4212 against official Schurter documentation to confirm the two-stage configuration and 42 A rating. Ensure the application requires a three-phase delta topology. Cross-reference certification requirements such as UL or VDE with project specifications before procurement.

Power Line Filter Modules Selection Notes

Select this component when a three-phase delta filter with a 42 A current rating is required. The two-stage design offers higher attenuation compared to single-stage units. Verify that the chassis mounting style and terminal block interface match the enclosure design. Confirm the 520 VAC rating aligns with the system voltage.

Power Line Filter Modules Part Context

This model belongs to the Schurter FMBC LL series of power line filters. It is designed for industrial environments requiring robust EMI suppression. The series typically includes various current ratings and configurations for three-phase applications. The FMBC-R91R-4212 specifically addresses high-current needs in delta-connected systems.

Power Line Filter Modules Replacement Considerations

Check for direct substitutes within the FMBC LL series with matching 42 A and 520 VAC ratings. Ensure any replacement maintains the two-stage topology and chassis mount form factor. Verify that certifications like UL and VDE remain valid for the substitute part.
