DATASHEET 3-Phase Filters FN 3311/FN 3310 Compact power line AC EMC/EMI filter High current 3-phase filter up to 2300 A Approvals & Compliances Extremely compact and light weight design Minimum installation foot print Performance optimised for standard purpose applications FN 3310 series without Cy capacitors to ground FN 3311 IT versions for use in IT power networks The FN 3311/FN 3310 poduct series of standard EMC/ EMI filters are based on Schaffners many years of expertise in filter design for all types of converter and inverter applications. Installed between the PV inverter and the power grid, the FN 3311/FN 3310 AC Performance indicators filters are used to influence positively the conducted emissions on the grid side to help to comply with the required emission standards. Features and benefits The FN 3311/FN 3310 series are the most compact dedicated high current AC filters, not only suitable for PV applications, but being an optimum fit with most modern PV inverter topologies. In addition the filters can be configured in a very flexible way to fulfil custom specific application requirements. All FN 3311/FN 3310 come in unsymmetrical housings, which help to prevent inverse installation and wrong Technical specifications electrical connection. Along with solar panel-side installed Schaffner DC EMC/EMI filters FN 2211/FN Maximum continuous operating voltage 3x 520/300 VAC for FN 3311 2210, the AC filters FN 3311/FN 3310 are key to meet 3x 520 VAC for FN 3310 the stringent international standards for electro- Operating frequency DC to 60 Hz magnetic compatibility and help to ensure a reliable Rated currents 250 to 2300 A 50C and fault-free operation of the entire PV system.
