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
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.
