ABB OT80F3C 1SCA105402R1001 I-0-II changeover switch disconnector 3P 80 A 690V

ABB OT80F3C (article 1SCA105402R1001) is a manual change-over switch rated at 80 A, purpose-built to transfer electrical loads between two power sources. It operates on an open transition principle, meaning there is a brief disconnection interval from both sources during the transfer sequence. The operating handle and shaft are not supplied with the unit and must be ordered separately to complete the assembly.

Technical specifications:

• Series: OT80F3C
• ABB article number: 1SCA105402R1001
• EAN: 6417019393377
• Rated current: 80 A
• Operation: Manual
• Transition type: Open transition
• Handle and shaft: Not included, must be ordered separately

Features and benefits:

• 80 A current rating enables switching of substantial electrical loads without an auxiliary power supply
• Open transition design gives a clear break between the two sources, preventing any cross-connection during changeover
• Manual operation means the switch functions independently of control voltage availability
• Separate handle and shaft ordering allows the installer to choose the configuration that suits the panel depth and layout

Applications:

• Changeover between a mains supply and a standby generator in commercial or industrial premises
• Manual source transfer in distribution boards and switchpanels where a brief supply interruption is acceptable
• Backup power selection in facilities requiring controlled, operator-initiated load transfer
• Industrial installations needing a clearly defined open-break transfer between two feed points

Also known as: ABB OT80F3C, OT80F3C 1SCA105402R1001, 80 A manual change-over switch, manual transfer switch, open transition changeover switch.
