Schaffner Chassis Mount 3 Phase Busbar EMI Filter 250A 520V AC 60Hz FN3311

Schaffner FN3311 is a high current EMI filter specifically engineered for 3 phase electrical systems, offering a maximum continuous current rating of 250 amperes and an operating voltage of 520 volts AC at 60 hertz frequency. This chassis mount filter utilizes a busbar termination style to facilitate secure and reliable electrical connections within industrial and electronic power components.

Designed to support photovoltaic inverter topologies and other standard industrial uses, the FN3311 series features a single-stage configuration housed within an unsymmetrical casing. This design helps prevent reverse installation and ensures proper electrical connectivity. It operates efficiently across a broad temperature range from -40°C to 100°C and generates a low leakage current of only 60 microamperes, enhancing energy savings.

The unit exhibits low power loss at 18 watts and occupies a minimal installation footprint due to its compact dimensions (170 mm length, 140 mm height, 195 mm depth). Its lightweight construction and performance characteristics make it suitable for applications requiring robust EMI suppression while maintaining low thermal and spatial impact.

This EMI filter is ideal for industrial, manufacturing, power electronics, and photovoltaic system applications. The chassis mount and busbar termination ensure mechanical robustness and ease of integration into existing electrical infrastructures.

High current 3-phase EMI filter for up to 250 A continuous current. Compact and lightweight chassis mount construction with busbar connection. Supports operating frequencies of 60 Hz with reliable performance. Wide operating temperature range from -40°C to 100°C for versatility.

Minimal power loss of 18 W enhances energy efficiency during operation. Low leakage current value of 60 μA reduces unnecessary power wastage. Unsymmetrical housing design prevents incorrect installation and wiring errors.
