Overview
The Schaffner FN3288HVIT-25-33-C26-R60 is a three-phase EMC power line filter designed for high-voltage industrial applications. It features a current rating of 25 to 27 A and operates within a voltage range of 305 to 760 VAC. The unit supports frequencies from 47 Hz to 400 Hz and includes an integrated neutral connection. With a leakage current of 3.7 mA, it ensures safety compliance while providing effective electromagnetic interference suppression in demanding environments.
Feature Summary
- Provides robust electromagnetic interference suppression for three-phase power systems
- Engineered for high-voltage operation up to 760 VAC
- Integrates a neutral conductor connection for comprehensive filtering
- Supports wide frequency ranges including 400 Hz aviation standards
Applications
- High-voltage industrial motor drives
- Aviation ground support equipment operating at 400 Hz
- Medical imaging power supplies requiring low leakage current
- Precision manufacturing automation systems
Procurement Notes
Verify the specific voltage and current requirements against the 305–760 VAC and 25–27 A ratings before procurement. Confirm that the 3.7 mA leakage current meets the safety isolation standards of your target application. Ensure the chassis mount terminal block interface matches your existing panel design constraints.
Selection Notes
Select this model when standard filters cannot handle voltages exceeding 530 VAC or require neutral filtering. The 400 Hz capability distinguishes it from standard 50/60 Hz units. Consider the physical dimensions and thermal management needs associated with its 25 A continuous current rating in enclosed spaces.
Part Context
This component belongs to the FN3288 series of power line filters manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series is recognized for high-performance EMI suppression in critical infrastructure. The HVIT suffix indicates specific high-voltage insulation and terminal configurations tailored for specialized industrial and aerospace sectors.
Replacement Considerations
Direct replacements are limited due to the unique high-voltage and 400 Hz specifications. Evaluate models with similar voltage ratings (up to 760 VAC) and current capacities (25–27 A). Verify that any substitute maintains the same neutral connection configuration and leakage current limits to ensure system compatibility.
