The Schaffner FN3288-100-35-C21-R65 is a three-phase EMC/RFI power line filter designed for chassis mounting. It supports a rated AC voltage of 530V relative to phase and 305V relative to neutral, operating at frequencies up to 60Hz. The unit handles a continuous current of 100A with a leakage current of 0.4mA. It features a two-stage configuration and utilizes terminal block connections. The component operates within a temperature range of -40°C to 100°C.
Verify the specific suffix codes against the official datasheet to ensure correct voltage and current ratings. Confirm that the terminal block style matches your wiring infrastructure. Check RoHS compliance status if required by local regulations. Ensure the chassis mounting dimensions fit your enclosure layout before procurement.
Select this model when high current capacity of 100A is required for three-phase applications. The 530V rating suits standard industrial power distributions. Consider the two-stage design if higher attenuation is needed compared to single-stage alternatives. Verify thermal management requirements given the 100A load and operating temperature limits.
This component belongs to the FN3288 series of EMC filters manufactured by Schaffner. The series is characterized by its modular design and suitability for demanding industrial environments. These filters are engineered to meet stringent electromagnetic compatibility standards for power electronics.
Check for FN3288 variants with different current ratings or voltage specifications. Ensure any substitute maintains the same terminal block interface and chassis mounting footprint. Verify that the replacement part meets the same leakage current and attenuation requirements.
