Surge and Lightning Protection
A surge is a transient electrical fluctuation that happens in a fraction of a second and can cause serious damage to electronic and electro mechanical equipment.
They can be caused by lightning strikes and local power utility company "spikes" which can enter your business or home through the electrical system ie. cable television, telephone wiring etc and attack any electrical equipment attached to them.
Hardwired Surge Filter
Since surge filters are connected in series, they must be suitably rated to carry the amount of electrical current that your equipment is using.
NPS provide a range of surge filters with load ratings from as low as 3 amp (typically used to protect a computer or a PLC) all the way up to 2000 amp (typically used to protect an entire installation. The cost and size of surge filters changes depending upon the load current rating.
