Description

A Surge Protection Devices (SPD) is an electrical device that is used to protect equipment against power surges and voltage spikes while blocking voltage over a safe threshold. Without a SPD, can create component issues, as permanent damage, reduced lifespan of internal devices, burned wires and data loss.
A SPD is usually installed in LT Switchgear (Class B), Electrical Distribution System (Class C) and communications structures, process control systems, other substantial industrialized systems (Class D).
The SPD Types described below are in accordance (paraphrased from) with UL 1449 Third Edition.

Type-3 SPDs: Surge Protection Device Type-3 – Point of Utilization

These SPDs are called, ‘Point of Utilization SPDs’, which are to be installed at a minimum conductor length of 10 meter (30 feet) from the electrical service panel unless they are evaluated at Type 3 SPDs. Type 3 SPD is characterized by a combination of voltage waves (1.2/50 μs) and current waves (8/20 μs).
