Mains power protection
ESP D/DS 10A & 32A Series (Single phase)
NOTE:
If your supply is fused at more than 32 Amps the ESP 120 M1, ESP 240 M1 or ESP 277 M1 are suitable.
Combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use on low
current (up to 10 or 32 A ) single phase systems to protect connected electronic
equipment from transient overvoltages on the mains supply, e.g. fire/intruder
alarm panels. Available for 90-150 Volts, 200-280 Volts and 232-350 Volts
supplies. For use at boundary LPZ 0 through to LPZ 3 boundaries 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)
–– Repeated protection in lightning intense environments
–– Compact space saving DIN housing for easy incorporation
in the protected system
–– 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
–– Advanced status (DS) version has remote indication facility
to a BMS via an active changeover volt-free contact to
show pre-failure warnings and potential phase loss
(i.e. power failure, blown fuses etc), and a flashing warning
of potentially fatal neutral to earth supply volts
Installation
Connect in-line with the power supply usually either
within the equipment panel (or for CCTV cameras, in an
enclosure close by), or on the fused connection that
supplies equipment.
To protect equipment inside a building from transients
entering on an outgoing feed (e.g. to CCTV cameras or to
site lighting) the protector should be installed as
close to where the cable leaves the building as possible.
Protectors should be installed either within an existing
cabinet/cubicle or in a separate enclosure.
