Protection of low-voltage AC circuits from the effects of transient over-voltages is best done in a step by step approach as no single device can totally protect an installation from a high voltage surge.

Ideally, a combination of surge diverters and surge suppressors should be used for complete protection. NHP stocks a large range of surge protection products from Cirprotec (including lightning surge protectors)to suit a number of surge protection requirements.

Additionally NHP offers an arc detection relay to protect both equipment and personnel in and around a switchboard from the risk of an arc flash.
