Low let-through voltage (enhanced protection to BS EN 62305) between
all sets of conductors (positive to negative, positive to earth and
negative to earth - Full Mode protection) allowing continuous
operation of equipment
Repeated protection in lightning intense environments
Visual indication of protector status
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

Features and benefits
Combined Type 2 and 3 tested protector (to BS EN 61643) for use on
DC systems to protect connected electronic equipment from
transient overvoltages on the mains supply, e.g. control equipment.
Available for 12, 24, 36 and 48 V DC systems. For use at boundaries
LPZ 1 through to LPZ 3 to protect sensitive electronic equipment.
Install in parallel, within the power
distribution board or directly on
the supply feeding the equipment.
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 positive,
negative and earth.

Accessories
Use on DC power distribution
systems to protect connected
electronic equipment from
transient overvoltages on the DC
supply, e.g. DC fed communications
or control equipment.
Application
For low current applications, the ESP H Series (4 A), ESP E Series (1.25 A) or ESP D Series
(300 mA) protectors may be suitable. For protection of photovoltaic (PV) systems up to
1000 Vdc, see our ESP PV Series.
