Procurement Notes

Verify the specific voltage rating (760 VAC) and current capacity (36 A) against your system requirements before procurement. Confirm that the screw mount style and terminal type match your enclosure design. Ensure the operating temperature range covers your environmental conditions. Cross-reference the datasheet for precise dimensional constraints and mounting hardware specifications to guarantee physical compatibility.

Selection Notes

Select this component when a robust, two-stage solution is required for three-phase AC lines. It is appropriate for applications needing significant noise attenuation in industrial settings. Consider the physical dimensions and weight if space is constrained. Evaluate the thermal management needs given the 100°C maximum operating temperature limit. Compare against single-stage alternatives if cost or size is a primary constraint.

Part Context

This part is part of Schurter's FMBC EP series, which focuses on efficient power conversion and voltage regulation through effective filtering. The series is engineered for industrial versions of power filters, providing reliable performance in harsh conditions. It complements other Schurter components like fuse holders and power line filters in complete power management assemblies.
