SURGE PROTECTION DEVICES

Surge Protection Devices to protect against the effects of indirect lightning strikes and high-energy direct lightning strikes. Indirect Lightning Strikes can result in voltage transients that can cause immense disruption to the electrical and data network. Spikes in voltage can distort data, and even corrupt hard drives to an irreversible extent.

Direct lightning strikes are protected by lightning current or equipotential bonding SPDs (Mains Type 1 SPDs & Signal/Telecom SPDs to Test Category D)
Indirect lightning strikes and switching transients are protected by transient overvoltage SPDs (Mains Type 2 and Type 3 SPDs and Signal/Telecom SPDs to Test Category C.
