ZoneMaster Series

Ideally suited to protect small to medium service entrance panels from
induced surges and transients

The ZoneMaster Series of surge
protection devices combines unparalleled

power handling capability, application
versatility, proven circuitry along with simple
installation, features which make these
units the ultimate mains power protection
solution. With configurations suitable for all
International supply voltages, ZoneMaster is
truly a versatile and flexible protection range.

ZoneMaster devices are modular in
construction. Individual modules are bolted

to a large surge return plate to minimise
transient impedance. These colour coded,
replaceable modules, with a UL 94-5V rated
plastic casing are supplied mounted within
a durable IP66 rated enclosure. ZoneMaster
units are easy to install via simple wall
mounting, although flush mounting is also an
option.

Large block, 3 terminal Metal Oxide
Varistor (MOV) protection technology

is utilised within the ZoneMaster range. The
dual protection circuits of ZoneMaster 150
devices provide full redundancy ensuring
the site is never unprotected. All ZoneMaster
units also include thermal and short circuit
fusing for additional safety.

Status indication is supplied as
standard, normally open/ normally closed

contacts change state to indicate a fault.
An optional remote monitoring unit is also
available providing audio and visual indication
of protector status, along with features such
as a test switch for checking the monitoring
circuitr y and an audio alarm silence switch.

The optional mains power filter has a
noise attenuation of 75dB at 100KHz- 100MHz
and will attenuate 6kV transients down to
just 200V. This mains power filter is UL 1283
Listed and all ZoneMaster devices have UL
1449 Listing for added peace of mind.
