Over Voltage Protection Device, 32A, 220V, 2/4 Pole

The term "pole" in the context of overvoltage protection refers to the number of conductors or paths that the protector can interrupt or control. In the case of an overvoltage protector, such as a surge protective device (SPD), the number of poles indicates how many conductors or phases the protector can protect simultaneously.

For example, a single-pole overvoltage protector is designed to protect a single-phase electrical system or a single conductor. It can handle the overvoltage protection for one line or phase.

On the other hand, a multipole overvoltage protector can provide protection for multiple phases or conductors simultaneously. For instance, a three-pole overvoltage protector is designed to protect a three-phase electrical system, which typically consists of three conductors or phases.

The number of poles in an overvoltage protector depends on the specific application and the electrical system it is intended to protect. It is essential to select an overvoltage protector with the appropriate number of poles that matches the configuration of the electrical system to ensure comprehensive protection against overvoltage events.
