Type 1 + 2 Surge Protection Devices

Add-on Block
We have recently launched type 1 + 2 surge protection devices (SPDs) that are designed to optimise arc extinction for both direct lightning strikes and for type 2 8/20 waveforms.

The device uses Spark Gap technology that has been further developed to limit follow current to a 500A peak to help minimise the problem of upstream MCBs or fuses tripping. It is also encapsulated to avoid any leakage current.

Spark Gap technology has a number of advantages when compared to the alternative Varistor technology. While SPDs based on Varistor technology discharge impulse energy, the reality is that about 2/3 of energy still flows through sensitive equipment for a short period of time. This has an obvious detrimental affect on that equipment.

The type 1 + 2 surge protection devices have good energy co-ordination to help prevent damage to sensitive electronic equipment, with T1 + T2 + T3 protection up to 5m with a 12.5kA μs impulse current and T1 + T2 for greater than 5m.
