ABB OT63F4C 1SCA105369R1001 I-0-II changeover switch disconnector 4P 63 A 690V

The ABB OT63F4C (article 1SCA105369R1001) is a 63 A manual change-over switch for transferring an electrical load between two separate supply sources. It operates on an open transition principle, meaning the load is briefly interrupted during the changeover rather than connected to both sources at the same time. The operating handle and shaft are not included and must be ordered separately, enabling the switch to be fitted to a range of panel and enclosure configurations.

Technical specifications:

• Series: OT63F4C
• ABB article number: 1SCA105369R1001
• EAN: 6417019393131
• Rated current: 63 A
• Operation: Manual
• Transition type: Open transition
• Handle and shaft: Ordered separately

Features and benefits:

• 63 A rated current suits substantial distribution loads in commercial and industrial installations
• Manual operation requires no auxiliary control power to perform a source changeover
• Open transition switching prevents momentary parallel connection of two supply sources, avoiding circulating currents between them
• Separate handle and shaft ordering allows the switch to be configured to match specific panel depths and front-face layouts
• Dedicated change-over function provides a clear, single-purpose means of selecting between two supply sources

Applications:

• Switching between mains utility supply and standby generator in commercial or industrial premises
• Manual source transfer in low-voltage distribution boards and switchgear panels
• Backup power selection in control cabinets where open transition is acceptable
• Supply switching in building services and facility management electrical installations
