Overview
The Schaffner FN3256H-36-33 is a three-phase (Wye) EMI/EMC power line filter designed for chassis mounting. It features terminal block connections for both input and output. The unit supports a rated current of 36 A and operates at frequencies from DC to 60 Hz. Voltage ratings include 480 VAC phase-to-phase, 520 VAC phase-to-phase, and 300 VAC phase-to-neutral. The device has a leakage current of 1 mA and functions within a temperature range of -25°C to +100°C.
Feature Summary
- Provides single-stage electromagnetic interference suppression for three-phase power systems.
- Utilizes terminal block interfaces for secure electrical connections.
- Engineered for direct chassis installation in industrial environments.
Applications
- Industrial machinery power conditioning
- Medical equipment noise filtering
- Data center power distribution units
Procurement Notes
Verify the specific voltage rating requirements against the datasheet, as sources list both 480V and 520V AC. Confirm that the terminal block configuration matches the system wiring diagram. Ensure the chassis mounting footprint aligns with the enclosure design. Check for updated certification marks such as UL or CSA if required by local regulations.
Selection Notes
Select this model when a three-phase Wye configuration is required with a 36 A capacity. The terminal block interface suits applications needing robust mechanical connections. Consider the thermal operating range of -25°C to +100°C for environmental compatibility. Verify that the 1 mA leakage current meets safety standards for sensitive loads.
Part Context
This component belongs to the Schaffner FN3256 series of power line filters. The series is characterized by compact designs suitable for various industrial EMC applications. The manufacturer is TE Connectivity / Schaffner. The part number suffix indicates specific terminal and voltage configurations within the family.
Replacement Considerations
FN3256H-36-33 is listed as an alternative to the discontinued FN356-36-33. Both are three-phase filters with similar current ratings. Verify dimensional compatibility and terminal block orientation before substitution.
