Mains power protection

ESP M1 Series

Combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use on mains

power distribution systems primarily to protect connected electronic equipment

from transient overvoltages on the mains supply, e.g. computer, communications

or control equipment. For use at boundaries up to LPZ

0

to protect against

flashover (typically the main distribution board location, with multiple metallic

services entering) through to LPZ 3 to protect sensitive electronic equipment.

Installation

Install in parallel, within the power distribution board or

directly (via fuses) on to the supply feeding equipment.

At distribution boards, the protector can be installed

either on the load side of the incoming isolator, or on

the closest outgoing way to the incoming supply. Connect,

with very short connecting leads, to phase(s), neutral and

earth. For TT installations, contact Furse.

Accessories

Weatherproof enclosures:

WBX 3

Use with single phase protectors

WBX 4

Use with three phase protectors

Full product range order codes can be

found on pages 17/8-17/9

NOTE:

If you desire a protector with an extra high maximum surge current use the ESP M2 or ESP M4 series. If your supply is fused at 16 amps, or less,

the in-line protectors (ESP 240 or 120-5A (or -16A) and their ready-boxed derivatives) may be more suitable. If you need to mount the display panel

separately from the main protector unit, use the ESP M1R series.

Features & benefits

–– Very low let-through voltage (enhanced protection to

IEC/BS EN 62305) between all sets of conductors (phase

to neutral, phase to earth, neutral to earth - Full Mode

protection)

–– Full mode design capable of handling partial lightning

currents as well as allowing continual operation of

protected equipment

–– Repeated protection in lightning intense environments

–– Innovative multiple thermal disconnect technology for safe

disconnection from faulty or abnormal supplies (without

compromising protective performance)

–– Three way visual indication of protection status and advanced

pre-failure warning so you need never be unprotected

–– Remote indication facility allows pre-failure warning to be

linked to a building management system, buzzer or light

–– Changeover active volt-free contact enables the protector

to be used to warn of phase loss (i.e. power failure,

blown fuses etc)

–– Flashing warning of potentially fatal neutral to earth

supply faults (due to incorrect earthing, wiring errors or

unbalanced conditions)

–– Robust steel housing

–– Base provides ultra-low inductance earth bond to

metal panels

–– Compact size for installation in the power distribution board

–– ESP 120 M1 and ESP 240 M1 have Network Rail Approval

PA05/02700 and PA05/01832 respectively. NRS PADS

reference 086/000556 (ESP 120 M1) and 086/047149
