Mains power protection

ESP D1 Series (Three phase)

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

to protect against flashover (typically the main distribution

board location, with multiple metallic services entering) through to LPZ 3 to protect

sensitive electronic equipment.

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.

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 32 Amps, or less,

the in-line protectors (and their ready-boxed derivatives) may be more suitable.
