£381.41
The ABB OT100F4C is a robust and reliable 4-pole manual change-over switch designed for safe switching between two electrical supplies or circuits in industrial and commercial installations. As part of the trusted ABB OT switch disconnector range, it provides dependable open transition switching for control panels, distribution boards, generator change-over systems and power transfer applications.
This front-operated, non-fusible change-over switch is designed for base mounting and panel integration, offering a practical solution for manual supply selection. Its compact construction, quick make and quick break switching mechanism, and protected terminal design support reliable operation in demanding low voltage electrical systems.
With a rated operational current of 100 A and a 4-pole configuration, the OT100F4C is suitable for manually transferring three-phase and neutral loads between independent supplies. Handle and shaft are ordered separately, allowing the operating mechanism to be matched to the enclosure design and installation requirement.
Manual change-over switches such as the ABB OT100F4C are used where an operator needs to select between two power sources, circuits or operating modes. The open transition design disconnects one source before connecting the other, supporting safe and controlled manual transfer.
The ABB OT range is widely used by panel builders, electrical contractors and machine manufacturers because of its robust construction, compact design and broad accessory compatibility. The OT100F4C is especially suitable for applications requiring a dependable 100 A 4-pole change-over switch for power distribution and supply selection.
