FN3270H-320-99

Overview

The Schaffner FN3270H-320-99 is a three-phase EMC/RFI power line filter designed for high-current industrial applications. It features a rated current of 320 A and operates at voltages up to 520 VAC with a frequency range of 0 Hz to 60 Hz. The unit utilizes busbar termination for both input and output connections, supporting Delta (3-wire + ground) configurations. Key electrical parameters include a leakage current of 6.9 mA and a maximum power loss of 6.8 W. The device is engineered for chassis mounting and functions within an operating temperature range of -25°C to +100°C.
