The Schaffner FN3288HV-50-53-C25-R65 is a three-phase EMC/RFI power line filter module designed for high-voltage industrial applications. It features a rated current of 50 A and operates at voltages up to 530 V AC (phase-to-phase) and 305 V AC (phase-to-neutral). The unit supports frequencies from DC to 60 Hz and utilizes a chassis mount configuration with solid safety connector blocks. Constructed in a compact book-style housing, it offers superior attenuation performance starting from 9 kHz. The device functions within an operating temperature range of -40°C to +100°C.
Verify the specific suffix codes against official Schaffner documentation to confirm voltage ratings and termination styles. Ensure the procurement specification matches the required phase configuration and current rating. Cross-reference the datasheet for compliance certifications such as UL and IEC standards before finalizing orders.
Select this model for applications requiring robust filtering in high-current environments. The book-style form factor is suitable for mounting close to inverters or motors where space is limited. Confirm that the input voltage does not exceed the 530 V AC rating and that the thermal environment stays within the specified operational limits.
This component belongs to the FN3288 series, which includes compact, high-performance EMC filters. The HV variant indicates suitability for higher voltage levels compared to standard models. The series is characterized by its slim profile and efficient noise suppression capabilities for industrial power electronics.
Consult official substitution guides for equivalent part numbers. Verify that any replacement maintains the same current rating, voltage class, and physical dimensions to ensure compatibility with existing chassis mounts and wiring configurations.
