Mains power protection

ESP M2/M4 Series

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

distribution board directly feeding electronic equipment such as computers,

communication and control equipment, particularly where a structural Lightning

Protection System (LPS) is employed. For use at boundaries up to LPZ

protect against flashover (typically the main distribution board location) through

to LPZ 3 to protect sensitive electronic equipment.

Installation

Install in parallel, within the power distribution board, 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. Phase/live

connecting leads should be fused with HRC fuses, a switchfuse,

MCCB or type ‘C’ MCB. For TT installations, contact Furse.

Accessories

Weatherproof enclosures:

WBX M2

For use with the ESP XXX M2

WBX M4

For use with the ESP XXX M4

Full product range order codes can be found on pages 17/8-17/9

NOTE:

For main distribution boards with multiple metallic services (gas, water, telecom/data lines) entering and for sub-distribution boards, the ESP M1 Series

are more suited. If your supply is fused at 16 Amps, or less, the in-line protection (ESP 240 or 120-5A (or -16A) and ready-boxed derivatives) may be suitable.

If you need to mount the display panel separately from the main protector unit, use the ESP XXX M2R or ESP XXX M4R.

Application

Use ESP M2 versions on main distribution board for buildings

with a Class III or IV structural LPS fitted or exposed 3 phase

power lines where no LPS is fitted. Use ESP M4 versions

on main distribution board for buildings with a Class I or II

LPS fitted.

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 and neutral to earth - Full Mode

protection)

–– Full Mode design capable of handling high energy partial

lightning currents as well as allowing continual operation of

protected equipment

–– Innovative multiple thermal disconnect technology, for safe

disconnection from faulty or abnormal supplies (without

compromising protective performance)

–– Three way visual indication of protection status

–– 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)

–– Unique flashing warning of potentially fatal neutral to earth

supply faults (caused by incorrect earthing, wiring errors

or unbalanced conditions)

–– Robust steel housing

–– Protector base provides ultra low inductance earth bond

to metal panels

–– Convenient holes for flat mounting
