ABB OT100F4C 4 Pole Manual Transfer Switch Assembly

ABB OT100F4C is a four-pole manual change-over switch rated for 100 A and up to 750 VAC, designed to switch between two sources in panel installations. It is a front-operated, open-transition change-over (I-O-II) unit, with a separate handle and shaft that must be ordered separately for installation. This 4-pole device provides isolation for all four conductors during transfer, making it suitable for panel-mount applications such as generator-to-grid transfers, standby power systems, and industrial power routing in control panels. As part of ABB’s OT line, the OT100F4C is specified for open-transition operation and a 100 A rating, with the mounting and mechanical interface designed to integrate with ABB’s accessory options for handles and shafts.
