ESP 415DT1/12.5 Series (Three phase)

Features & benefits
Very low let-through voltage (enhanced protection to IEC/
BS EN 62305) between phase and neutral conductors,
where sensitive equipment is connected
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  Application
ESP 415DT1/12.5 for use with Class I or II Lightning
Protection Systems LPS where there are multiple metallic
services to the building or on exposed overhead three
phase power lines where no LPS is fitted
ESP 415DT1/12.5 for use with Class III or IV LPS or where
the LPS and service line information is unknown and so
SPD impulse current Iimp cannot be calculated (minimum
12.5kA Iimp required)
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
