TSC-0912 - 09.10.12
Very low let-through voltage (enhanced protection to 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)
Robust steel housing
Base provides ultra-low inductance earth bond to metal panels
Compact size for installation in the power distribution board
ESP 120 M1 and ESP 240 M1 have Network Rail Approval PA05/02700
and PA05/01832 respectively. NRS PADS reference 086/000556
(ESP 120 M1) and 086/047149 (ESP 240 M1)
Features and benefits
Combined Type 1, 2 and 3 tested protector (to BS EN 61643) for use
on mains power distribution systems primarily to protect connected
electronic equipment from transient overvoltages on the mains
supply, e.g. computer, communications or control equipment. For use
at boundaries up to LPZ
0
B
to protect against flashover (typically the
main distribution board location, with multiple metallic services
entering) through to LPZ 3 to protect sensitive electronic equipment.
Install in parallel, within the power
distribution board or directly (via
fuses) on to the supply feeding
equipment.
Installation
Weatherproof enclosures
WBX 3
Use with single phase protectors
WBX 4
Use with three phase protectors
Accessories
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 phase(s),
neutral and earth.
For TT installations, contact Furse.
ESP 415 M1 installed within a control panel on the
mains input to protect the panel’s control systems.
Note the remote indication connection (top of protector)
