Surge Suppressor
A Surge Arrestor (aka. Surge Protector/Suppressor) is a device that acts essentially as safety release valve should a very large in-rush of voltage/current find its way into a building and into the PDU.
Surges can be forms of atmospheric disturbance such as a lightning strike hitting a building (LEMP - Lightning Electromagnetic Pulse) and internal causes such as large devices switching On /Off (SEMP - Switching Electromagnetic Pulse)
A PDU Surge Arrestor intersects the incoming mains feed across the Live, Neutral and Earth terminals. When a large transient voltage enters the PDU through any one of the terminals the Surge Protector attempts to re-route this transient voltage away from the PDU and back down the incoming mains cable. This creates a temporary dead short and moves the brunt of the transient voltage to ground.
Surge Protection comes in various forms and offers different levels of protection. This PDU Surge Arrestor is a last stage (or Terminal Stage) Surge Protector as it is located nearest the end-of-the-line terminal equipment.
This device can be added to any of our PDU's at very little cost.
