Mains power protection
ESP M1R, M2R & M4R 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. Remote display allows both display and
protector unit to be mounted in their optimum positions. 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
Installation of the protector unit is identical to the ESP M1,
M2 or M4. Position remote display, making sure that the
cable is long enough, is unimpeded within the cabinet, and
allows a minimum of 60 mm behind the panel front (for the
interconnection cable). For TT installations, contact Furse.

Features & benefits
–– The remote display means the protector can be mounted
close to the incoming feed or first way on the
distribution board and the display in an easily visible
position, e.g. on front of cabinet
–– 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 abnormal or faulty supplies
–– Remote display gives three way visual indication of
protection status
–– Plug-in cable connections between protector and display
enable easy connection (1 m cable supplied as standard)
–– 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), and sturdy ABS
housing (display)
–– Base provides ultra-low inductance earth bond to
metal panels
–– Remote display comes with integral fixings and a panel
drilling template
Application
ESP M1R: main distribution board for buildings with multiple
metallic services (e.g. gas, water, telecoms) and sub-
distribution boards feeding sensitive equipment. ESP M2R:
main distribution board for buildings with Class III or IV LPS
fitted or exposed 3-ph power lines where no LPS is fitted.
ESP M4R: main distribution board for buildings with a Class I
Parallel connection of ESP 415
M1R to three phase star (4 wire
and earth) supplies (fuses not
shown for clarity)
