Mains power protection
ESP D1 Series (Single 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
–– 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

STATUS
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. 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 live, neutral and earth.
Accessories
Weatherproof enclosure:
WBX D4
Full product range order codes can be found on pages 17/8-17/9
NOTE:
If you desire a protector with an extra high maximum surge current use the ESP M2 or ESP M4 series. If your supply is fused at 16 Amps, or less,
the in-line protectors (and their ready-boxed derivatives) may be more suitable.
Series connection of ESP 120 D1,
ESP 240 D1 and ESP 277 D1 to
single phase supplies up to 125 A
(fuses not shown for clarity)
Parallel connection of ESP 120 D1,
ESP 240 D1 and ESP 277 D1 series
to single phase supplies (fuses not
shown for clarity)
Combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use on single
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. 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.
