FMBC-A91R-4212

Power Line Filter Modules Overview

The FMBC-A91R-4212 is a three-phase (Delta) EMC/EMI line filter from the Schurter FMBC NEO series. It supports a rated current of 42 A and operates at voltages up to 520 V AC, with compatibility for 480 V AC systems at 50 Hz or 60 Hz frequencies. The unit features a two-stage filtering architecture designed for effective noise suppression. It utilizes screw terminal connections for secure electrical interfacing and is constructed for chassis mounting. Key electrical parameters include a maximum leakage current of 33 mA and a power loss of 6.8 W under rated conditions.

Power Line Filter Modules Procurement Notes

Verify that the specific application voltage matches the 480V or 520V AC rating. Confirm the load current does not exceed the 42A limit. Ensure the mounting surface accommodates the chassis mount style and that the wiring method aligns with the screw terminal requirements. Check for required certifications such as UL or VDE depending on regional compliance standards.

Power Line Filter Modules Selection Notes

Select this model when high-current three-phase protection is required. The Delta configuration suits ungrounded or corner-grounded systems. Consider the thermal performance given the 6.8W power loss. Verify physical dimensions against available panel space. Compare leakage current specifications if sensitive equipment is connected downstream.
