FN2412-45-33

Overview

The FN2412-45-33 is a single-phase EMC/RFI power line filter manufactured by TE Connectivity / Schaffner. It features a rated voltage of 250 VAC and a current rating of 45 A, designed for operation within a frequency range of 0 Hz to 400 Hz. The unit utilizes terminal block termination and is configured for DIN rail mounting. Key electrical specifications include a leakage current of 2.6 mA and compliance with UL, CSA, and IEC/EN standards. The device operates effectively between -25°C and +100°C.

Feature Summary

• Provides exceptional conducted attenuation performance through chokes engineered with high saturation resistance.
• Ensures excellent thermal stability and damping properties suitable for applications requiring high radio interference suppression.
• Designed for compact installation with minimum space requirements on standard TS 35 DIN rails.

Applications

• Industrial machinery power conditioning
• Medical equipment input stages
• General purpose AC/DC power supply filtering

Procurement Notes

Verify the specific current rating against project requirements, as the model number indicates 45 A, while similar variants like the FN2412H-32-33 are rated at 32 A. Confirm that the terminal block interface matches existing wiring infrastructure. Ensure the DIN rail mounting style is compatible with the intended enclosure design. Cross-reference certification marks such as UL and CSA with local regulatory mandates before finalizing procurement.

Selection Notes

Select this component when high current handling up to 45 A is required in a single-phase configuration. The terminal block connection method is preferred over quick-connect types for robust mechanical security in high-vibration environments. Consider the operating temperature range of -25°C to +100°C for environmental suitability. The compact form factor makes it ideal for space-constrained industrial panels where DIN rail integration is necessary.
