ABB OT125F3C 1SCA105037R1001 I-0-II changeover switch disconnector 3P 125 A 690V

The ABB OT125F3C (article 1SCA105037R1001) is a 125 A manual change-over switch for transferring electrical loads between two supply sources. Switching is performed by hand and follows an open-transition sequence, meaning power is briefly interrupted before the alternative source is connected. The handle and shaft required for operation are not included and must be ordered separately, allowing the unit to be adapted to different panel depths and mounting arrangements.
