While the fitting of surge protectors on a main supply board is no longer obligatory,
Wattronics (Pty) Ltd recommends that for peace of mind and
protection of sophisticated electronic equipment used in both home and office
that proper surge protections is fitted on both the live and neutral connection
entering the mains board.

International specification (IEC 60664-1) to which most of today’s equipment will
comply specifies the maximum differential mode surge that the equipment
should be able to withstand without damage is 1500 Volt. A surge or a spike is a
transient voltage that last for only a split second.
There are two types of protectors fitted. On the live a metal oxide varistor
(MOV) unit is recommended and for the neutral a spark gap or as it is also referred
to an N-PE type. The value in fitting both is in the way they are configured
to ensure that surges over 1500V are bled off to earth and don’t travel
around the indoor wiring.
In the past it was common to fit the MOV type protectors between line and earth
and neutral and earth.

The Surge Essential™ is a front line device in the current climate of load shedding and also protects equipment against normal surge damage, 3 phase neutral problems, lightning strikes and noisy power supplies. The Surge Essenial gives 100% switch on surge protection and auto resets to give you complete peace of mind.
