188 / 300
ESP D1 Series (Three Phase)
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 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
ESP XXX D1R or ESP XXX D1R/LCD units (where XXX = 208, or 415, or
480) have a remote display that allows the protector to be mounted
close to the incoming feed or distribution board with the display being
mounted in a visible position e.g. at the front of the panel
ESP XXX D1/LCD or ESP XXX D1R/LCD units have backlit LCD intelligent
display offering clear status information that can be rotated for side
mounting to facilitate short connecting leads
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)
Through terminal facility allows series connection on low current
supplies to eliminate high additive voltage associated with connecting
leads on units installed in parallel
Compact space saving DIN housing
Features and benefits
Combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use
on three phase mains power distribution systems primarily to
protect connected electronic equipment from transient overvoltages
on the mains supply, e.g. computer, communications or control
equipment. Innovative remote display options allow both protector
and display to be mounted in their optimum position. For use at
boundaries up to LPZ
0
B
to protect against flashover (typically the
main distribution board location, with multiple metallic services
entering) through to LPZ 3 to protect sensitive electronic equipment.
Install in parallel, within the power
distribution board or directly (via
fuses) on to the supply feeding
equipment. Can be installed in
series for low current supplies - see
installation instructions.
For ESP D1R or D1R/LCD units,
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).

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 phases,
neutral and earth.
