The Schaffner FN3280H-36-33-R69 is a three-phase EMC line filter designed for industrial machinery applications. It supports a rated current of 36 A and operates at voltages up to 520 VAC with frequencies ranging from DC to 60 Hz. The unit features a two-stage configuration utilizing terminal block connections for both input and output. Designed for chassis mounting, it accommodates WYE (4-wire plus ground) systems. The component functions within an operating temperature range of -25°C to +100°C.
Verify the specific suffix R69 against project requirements to ensure compliance with IEC 60204-1 standards for complex machines. Confirm that the terminal block termination style matches existing wiring infrastructure. Validate voltage and current ratings against the actual load profile to prevent derating issues. Ensure chassis mounting provisions align with the enclosure design specifications.
Select this model when high-performance filtering is required for multi-axis industrial drives. The two-stage design offers superior attenuation compared to single-stage alternatives. The R69 suffix is critical for applications demanding specific machine safety compliance. Consider the physical dimensions and terminal block layout during the initial system integration phase to ensure proper fitment.
This component belongs to the FN3280 series, which provides specialized filtering solutions for demanding industrial environments. The series is engineered to handle significant electromagnetic interference generated by variable frequency drives and motor controllers. It serves as a key element in maintaining signal integrity and regulatory compliance in heavy-duty manufacturing equipment.
