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 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
Features and benefits
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
A
to protect against flashover (typically the main distribution
board location, with multiple metallic services entering) through to
LPZ 3 to protect sensitive electronic equipment.
ESP M1R: main distribution board
for buildings with multiple
metallic services (e.g. gas, water,
telecoms) & 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 or II LPS.
Application
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).
