SG – Spark Gap Surge Arresters

Use Spark Gap Surge Diverters for point of entry protection at main switchboards where direct strike protection is required.

Carbon disk spark gaps are a robust and proven technology designed to handle long duration surges. The low resistance design minimises the energy dissipation within the device.

Two models are available with either 50 kA or 110 kA of impulse current handling per phase for even the most extreme lightning environments.

The Novaris spark gap diverters are a sealed unit and do not exhaust hot ionised gas into the switchboard.

HSG – Hybrid Spark Gap Arresters

Use Hybrid Spark Gap high energy surge diverters for point of entry protection at main switchboards where grid instability is an issue.

The Hybrid Spark Gap design combines a spark gap and MOV in series to improve the overvoltage tolerance of the surge protector. This combination allows the HSG to be exposed to continuous over voltage of up to 480V while still providing a low voltage protection level.

Unlike standard spark gaps the Hybrid Spark Gap has no follow on current.
