Surge Protection


For cost-effective risk management and unrivalled peace of mind, talk to us about power surge protection products from ERICO. With appropriate power surge protectors and surge diverters in place, you can avoid the devastating and expensive damage a power spike from any source can cause.

ERICO’s surge protection devices protect against damaging electrical surges on power and communications lines caused by lightning, industrial machinery and other switching events.

Avoiding weak links

We recommend a coordinated approach to surge protection. The first stage of defence is installing primary protection devices at the mains supply service entrance. This should be followed by secondary protection at distribution branch panels and where necessary, at point-of-use applications, such as power outlets for electronic equipment.

We also recognise the need to provide effective surge protection on cables supplying telecommunications, signal and data management equipment.

The right level of investment

Compared to sensitive electronics, robust equipment such as lighting and air conditioning is not as vulnerable to power surges and is typically less essential to a site’s operation. However, significant damage can occur to any system from surges caused by lightning within a radius of several kilometres, or from switching induced surges.

The impact can range from damaged electrical or electronic systems to data loss, equipment destruction or injury to personnel. While the cost of replacing some equipment may be relatively minor, the cost of losing an essential service or the revenues associated with a facility or plant because it was shut down can be enormous.
