4P 630A Automatic Transfer Switch 110V 220V Grid to AC Generator

Product Overview

This aftermarket replacement automatic transfer switch is a 4-pole, 630A unit designed for 110V / 220V systems to transfer load between grid power and an AC generator. An automatic transfer switch monitors the incoming power supply and shifts the connected load from one source to another when the primary source is lost or restored. This switch is intended for industrial applications where changeover between grid and generator supply is required.
