|  For customers
who demand a protector rated for a maximum surge current greatly in excess
of the probable worst case (BS 6651, IEEE C62.41).
Suitable for three phase
(346-484V) supplies, whatever their supply current.
For a maximum surge current
rating of 60kA (unit total 240kA) use ESP 415 M2.
For a maximum surge current
rating of 120kA (unit total 480kA) use ESP 415 M4.
The, lower cost, ESP
415 M1 has a maximum surge current of 30kA (120kA unit total) and
is suitable for use on most three phase (346-484V) supplies. Protectors
for single phase and other voltage supplies can be found here.
If your supply is fused at 16 amps, or less, the protectors here
may be more suitable (Note these have a lower maximum surge current of
10kA).
Application
Use these units at the main low voltage distribution board for extra
high surge current protection. Typical uses include the protection of:
computer equipment
transmitter/receiver systems
uninterruptible power
supplies (UPS)
drives and inverters
programmable logic controllers
(PLC)
medical equipment
Features and benefits
 Designed to protect
and survive in lightning intense environments.
Very low let-through
voltage restricts dangerous transient overvoltages to below the damage
levels of equipment circuitry.
Protection between
all sets of conductors (phase to neutral, phase to earth and neutral to
earth) ensures total protection, closing all transient paths to equipment.
Extra high maximum
surge current of 60kA (240kA unit total ) for ESP 415 M2 and 120kA (480kA
unit total) for ESP 415 M4.
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
(without compromising protective performance). 
|
Three way visual indication
of protection 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.
Changeover active volt
free contact enables the protector to be used to warn of phase loss (ie
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.
Simple parallel connection.
Protector base provides
ultra low inductance earth bond to metal panels.
Convenient holes for
flat mounting.
Compact size for installation
in the power distribution board.
Straightforward, comprehensive
installation instructions with every unit.
Maintenance free.
5 year warranty.
