ABB OT40F3C 1SCA104913R1001 I-0-II changeover switch disconnector 3P 40 A 690V

ABB OT40F3C (article 1SCA104913R1001) is a 40 A manual change-over switch that allows an operator to transfer a load circuit between two power sources by hand. It works on an open transition basis, meaning the existing supply is fully disconnected before the alternate source is connected. The operating handle and shaft are not supplied with the unit and must be ordered separately.

Technical specifications:

• Series: OT40F3C
• ABB article number: 1SCA104913R1001
• EAN: 6417019390536
• Rated current: 40 A

• Transition type: Open transition (break-before-make)
• Handle and shaft: Not included - must be ordered separately

Features and benefits:

• Manual operation puts the operator in direct control of source switching, requiring no external power or control signal to actuate
• Open transition switching prevents any momentary parallel connection between the two supply sources during changeover
• Separate handle and shaft ordering allows the installer to select the actuator configuration that suits the panel layout and enclosure depth
• 40 A current rating covers a wide range of single and multi-circuit loads in industrial and commercial installations

Applications:

• Manual transfer between mains utility supply and standby diesel generator
• Dual-supply source selection in industrial control panels and switchboards
• Backup power changeover in commercial buildings and facilities
• Manual load transfer in distribution boards where automated transfer is not required
