ABB OT125F3C Manual Change-Over Switch 125A 3P
I. Product Overview
The ABB OT125F3C is a manual change-over switch from the OT series manufactured by ABB, model OT125F3C. This switch is a 3-pole manual change-over switch with rated current 125A, featuring I-0-II three positions and open transition, used for manual dual power switching and circuit isolation.
The OT series is ABB's low-voltage switch product series of manual change-over switches, covering currents from 16 to 3200A, compliant with IEC 60947-3 standard. This series uses modular design, with handle and shaft ordered separately, allowing selection of operating mechanisms based on different mounting methods.
The OT125F3C is a non-fusible disconnector with base mounting, protection rating IP20. It is suitable for industrial power distribution systems, control circuits and equipment power switching applications.
