|  Remote
display allows both display and protector unit to be mounted in their
optimum positions.
Advanced protector for
mains power supplies and power distribution systems.
Available for three-phase
supplies of 346-484 volts.
For three phase applications where a remote
diplay is unecessary refer to the ESP *** M1
series or the ESP *** M2/M4 series for extra
high surge current protection.
Application
Typically install in large three-phase cubicle switchboards to protect
connected electronic systems, eg computer, communications and control
equipment.
Features and benefits
 The remote display
means the protector can be mounted close to the incoming feed or first
way on the distribution board and the display in an easily visible position,
eg on front of cabinet.
Very low let-through
voltage between all sets of conductors (phase to neutral, phase to earth
and neutral to earth).
Maximum surge current
greatly in excess of the 10kA worst case indicated in BS 6651 and IEEE
C62.41.
Repeated protection
in lightning intense environments, with 20 years predicted lifetime.
Innovative new Sovtrip™
multiple thermal disconnect technology, anticipates standards authorities'
future demands, for safe disconnection from faulty or abnormal supplies.
Slimline, remote display
gives thee way visual indication of protection status.
1m cable for connection
between protector and display as standard.
Plug-in cable connections
between protector and display enable easy connection.
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).
Unique flashing warning
of potentially fatal neutral to earth supply faults (caused by incorrect
earthing, wiring errors or unbalanced conditions).
Robust steel housing
for the protector, and sturdy ABS housing for the display.
Protector base provides
ultra low inductance earth bond to metal panels.
Protector unit comes
with convenient holes for flat mounting.
|
Remote display is easily
installed with standard drilling tools.
Remote display comes
with integral fixings and a panel drilling template.
Compact size for installation
in the power distribution board.
Maintenance free.
Installation
Installation of the protector unit is identical to the ESP 415 M1.
Position remote display, making sure that the cable is long enough, is
unimpeded within the cabinet, and allows a minimum of 60mm behind the
panel front (for the interconnection cable). Use template (found in installation
instructions supplied with each unit) to mark holes. Drill, screw in place
and plug in connection cable on back of display from inside the cabinet.
Suitable Accessories
In applications where a 1 metre connecting cable is insufficient, a
4 metre cable (ESP RLA-4) can be ordered separately.
