Overview
The Schaffner FN351-36-47 is a three-phase (Delta) EMC/EMI line filter designed for chassis mounting. It supports a rated current of 36 A and operates within a frequency range of DC to 60 Hz. This single-stage filter is part of the FN351 series, which was among the first motor drive EMC filters introduced to the market. The component is engineered for high-power applications, providing effective noise suppression in industrial environments.
Feature Summary
- Designed specifically for motor drive EMC filtering applications
- Single-stage configuration for efficient noise attenuation
- Robust chassis mount construction for industrial stability
Applications
- Motor drive systems requiring EMC compliance
- Industrial power distribution networks
- Three-phase equipment with Delta configurations
Procurement Notes
Verify the specific datasheet version for the FN351-36-47 to confirm terminal block specifications and exact physical dimensions. Ensure compatibility with existing chassis mounting holes and terminal connections before integration. Cross-reference approval certifications such as CSA, ENEC, or UR if required by local regulatory standards for your specific installation site.
Selection Notes
Select this component when a dedicated single-stage solution for three-phase Delta systems is required. The 36 A rating suits moderate to high-power motor drives. Consider the chassis mount form factor for direct panel integration. Verify that the operating frequency range up to 60 Hz aligns with the system's power supply characteristics.
Part Context
The FN351 series represents a foundational product line from Schaffner, recognized as one of the earliest specialized EMC filters for motor drives. Its widespread adoption has led to numerous imitations, yet it remains a benchmark for reliability in industrial noise suppression. The FN351-36-47 variant specifically addresses the needs of three-phase Delta configurations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative Schaffner models within the FN351 series or consult manufacturer engineering support for direct equivalents based on specific electrical and mechanical constraints.
