ESF SERIES

COMPACT 2-PORT

SURGE FILTERS

FEATURES

• Compact solution for Class II / Cat

B,C & D, Point of Entry, distribution

board and sub board surge protection

• 2 mode protection L-N or L-E

& N-E

• High kA rating per phase 100kA,

Imax

• Exceptionally low let through voltage

<600V @ 3kA / 8/20us,

<800V @ 50kA / 8/20us, Inom

• 50A to 80A single and three phase

models

• Fully enclosed and gear tray versions

to suit switch boards

• Can be configured for 3:1 phase

bypass loads

• Available in TN & TT systems

versions

• Eliminates RCD/ELCB tripping by

being installed at the service bus

UPSTREAM of RCD/ELCB’s. ( In

accordance with latest wiring rules

recommendations.)

• Cost effective solution where multiple

20A series filters cause cost over run

and increased cabinet foot print.

APPLICATIONS

• Telecommunications systems

• Medical equipment

• Industrial equipment

• Data centres

• Control systems

• Switch boards

applicable to TT, TN-C, TN-S and TNC-S power systems nominally rated between 380 and 440V. FUNCTIONAL DESCRIPTION The ESF series surge filters are Class II, single and three phase, 2 port SPDs, designed to provide complete site surge protection in a compact footprint. These models utilize UL1449 ed3 certified thermallyfused MOV devices in conjunction with air-wound inductors to provide a current-limited output, coordinated to surge levels below 3kA.

CABLE LENGTHS AND SIZES GUIDELINES FOR PLANNING YOUR SURGE PROTECTION We recommend that the specifier and installer become familiar the standards applicable to the equipment and site, prior to any final product selection and placement. Correct product selection according to risk and location category is essential to a successful solution. This may also involve changing some aspects of existing electrical infrastructure to ensure an effective result.

SINGLE POINT EARTHING At the point of entry, the earth conductor is the common surge conductor. To prevent damage and minimize personal risk, it is imperative that all grounding systems are brought together at the supply connection point. As an example, the earth provided for equipment to be connected to this SPD must be connected to the same point as the SPD’s earth, back at the source. DO NOT daisy chain earth from the SPD to the device that the SPD is protecting.
