FN3258H-16-44

Overview

The Schaffner FN3258H-16-44 is a three-phase EMC/EMI line filter designed for chassis mounting. It supports a rated current of 16 A and operates at frequencies up to 60 Hz with a voltage rating of 520 VAC. The unit utilizes terminal block connections for both input and output. Key electrical specifications include a leakage current of 4.3 mA and a power loss of 11.8 W. Physical dimensions are 220 mm in length, 45 mm in width, and 70 mm in height. It functions within an operating temperature range of -25°C to +100°C.

Feature Summary

• Single-stage filtering architecture for three-phase delta configurations
• Compact ultra-compact chassis mount design
• Terminal block interface for secure wiring

Applications

• Industrial machinery electromagnetic compatibility
• Power supply noise suppression in delta systems
• Equipment requiring low leakage current isolation

Procurement Notes

Verify the specific suffix 'H' against official datasheets to confirm it denotes the high-voltage or specific variant configuration rather than a standard model. Ensure terminal block compatibility matches existing panel hardware. Confirm regulatory certifications such as UL and CSA are required for the target deployment region before finalizing orders.

Selection Notes

Select this component when a three-phase delta system requires a compact filter with low leakage current. The 16 A rating suits moderate load applications. Verify that the 520 VAC rating aligns with the network voltage. Consider the chassis mount style for enclosure integration where space is limited compared to larger industrial filters.

Part Context

This part belongs to the FN3258 series, characterized by ultra-compact form factors for three-phase applications. The 'H' suffix typically indicates specific internal construction or voltage handling capabilities distinct from the base FN3258 models. It serves as a specialized solution for dense packaging requirements in industrial power electronics.

Replacement Considerations

FN3258-16-44 is a listed alias for this component. Verify if the non-H variant meets the specific voltage or insulation requirements of the application before substitution.
