ESP D1 Series (Three phase)

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
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
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
Installation
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. For TT installations, contact Furse.
