Overview
The FN3287-20-33-C33-R65 is a three-phase EMC/RFI power line filter from the Schaffner FN3287 series. It features a rated current of 20 A and a voltage rating of 530 VAC. The unit utilizes terminal block termination for both input and output connections, supporting Delta wiring configuration (3 wires plus ground). Designed for chassis mounting, it operates within a frequency range of 0 Hz to 60 Hz. The component complies with UL 60939-3 and IEC 60939-3 standards.
Feature Summary
- Provides EMI/EMC filtering for three-phase AC power lines
- Compact slim book design optimized for space-constrained installations
- Terminal block interface facilitates secure electrical connections
Applications
- Industrial machinery power conditioning
- Three-phase motor drive systems
- Power distribution units requiring EMI suppression
Procurement Notes
Verify that the specific ordering suffix matches the required terminal block configuration and flange dimensions. Confirm compliance requirements against local regulatory standards such as UL or CE before procurement. Ensure the rated current and voltage parameters align with the system's operational limits to prevent component failure.
Selection Notes
Select this model when a compact three-phase filter is required for currents up to 20 A at 530 VAC. The terminal block termination is suitable for applications requiring robust mechanical connections. Consider the physical dimensions and chassis mounting style during enclosure design to ensure proper fit and thermal management.
Part Context
This component belongs to the FN3287 series, which offers various current ratings and configurations. It serves as an EMI/RFI suppression solution for industrial environments. The series is designed to meet stringent electromagnetic compatibility standards while maintaining a small footprint for integration into modern power electronics systems.
Replacement Considerations
Cross-reference part numbers within the FN3287 series for alternative current ratings. Verify that any substitute maintains the same terminal block type and mounting style to ensure mechanical compatibility without redesigning the installation panel.
