100a 4 Pole Automatic Change Over

A 100A 4-pole automatic changeover switch (ATS) is an electrical device that automatically transfers power supply from a primary source (e.g., utility grid) to a secondary source (e.g., generator) in the event of a power outage, and back again when the primary source is restored. Key features: 100A: Indicates the maximum current it can safely handle. 4-pole: Means it switches all four electrical conductors (three phases and neutral) simultaneously, making it suitable for three-phase power systems. Automatic: Automatically detects power loss and restoration, initiating the transfer without manual intervention. Changeover Switch: Its primary function is to switch between two different power sources.
