Geya 100A Automatic Transfer Changeover Switch W2R-4P Single Phase/3Phase by Lumett

The Geya 100A Automatic Transfer Changeover Switch W2R-4P Single Phase/3Phase is designed to automatically switch compatible electrical loads between two available power sources. It provides a practical solution for installations that use a primary supply alongside a standby source such as a generator, inverter, or compatible solar power system.

The W2R-4P configuration provides four-pole switching and is suitable for compatible three-phase applications requiring neutral switching. Its automatic transfer function helps reduce the need for manual intervention when transferring between power sources.

With a 100A rated-current option, this changeover switch can be used in appropriately sized residential, commercial, and electrical distribution systems. The actual application should be determined by the system load, voltage, protection requirements, wiring configuration, and manufacturer’s specifications.
