ABB OT63F3C 1SCA105338R1001 I-0-II changeover switch disconnector 3P 63 A 690V

The ABB OT63F3C (article 1SCA105338R1001) is a 63 A manual change-over switch for selecting between two supply sources without the need for auxiliary control power. It operates on an open transition principle, meaning the load circuit is briefly de-energised during the transfer between positions. The handle and shaft are not included and must be ordered separately, allowing the actuator length and orientation to be matched to the enclosure or panel layout.

Technical specifications:

• Series: OT63F3C
• ABB article number: 1SCA105338R1001
• EAN: 6417019392974
• Rated current: 63 A
• Poles: 3
• Operation: Manual
• Transition type: Open (load is de-energised momentarily during source transfer)
• Handle and shaft: Not included - must be ordered separately

Features and benefits:

• Manual operation provides direct source control with no reliance on auxiliary voltage or control circuits
• Open transition switching prevents any momentary parallel connection of two supply sources, eliminating cross-connection risk
• Separately supplied handle and shaft allow the shaft length and mounting position to be configured to suit the specific panel depth and layout
• 63 A current rating covers a broad range of three-phase distribution and load circuits in industrial and commercial installations

Applications:

• Manual transfer between a mains supply and a standby or generator feed in distribution boards
• Source selection in motor control centres and industrial control panels with two incoming supply options
• Generator changeover duties in commercial buildings where manual switching is acceptable
• Panel assemblies where a custom shaft length is needed to position the operating handle at the correct mounting depth
