Product Features

The Eaton ESFi Surge Filters are Class II, single and three phase, 2 port SPD’s, designed to provide complete site surge protection in a compact footprint.  These models utilize UL1449 ed3 certified thermally-fused MOV devices in conjunction with air-wound inductors to provide a current-limited output, coordinated to surge levels below 3kA.  This means that all downstream power circuits are protected to ANSI/IEEE C62.41 Category B level, the common level that medium power LV loads (UPS, rectifier, industrial machines) are designed to accept. The design results in an exceptionally low let through voltage (<600V, 3kA, 8/20us). In addition, the units also provide filtering of line harmonics, noise and RF transmitters with a cut off frequency of <10KHz and a nominal attenuation of 48dB above 1MHz.

The units can be supplied in gear-tray format for installation into a switchboard, or enclosed in an IP54 enclosure.  When installed in compliance with the manufacturer’s instructions and applicable standards, this unit provides a high degree of protection to connected loads.  Models are offered in 1 or 3 phase for TT or TN-based power systems in the range of 50A to 80A.
