Why Choose the ABB OT160KLAA3C Enclosed Change-Over Switch?
The ABB OT160KLAA3C is a heavy-duty 160 A enclosed change-over switch designed for manual switching between two electrical supplies or circuits in industrial and commercial low-voltage installations. It belongs to ABB's 311019-Metal Enclosed (Loadbreak) product group and combines ABB OT change-over switching technology with a robust steel-sheet enclosure.
The OT160KLAA3C provides 3-pole change-over switching with clearly defined I-O-II positions, enabling manual selection between two sources with an OFF position between them. Its steel-sheet enclosure provides IP54 protection, while the front-operated black pistol-type handle gives clear visual indication of the selected switching position.
Rated at 160 A AC-22A up to 690 V AC and 135 A AC-23A up to 415 V AC, the OT160KLAA3C is suitable for substantial distribution and transfer applications. The enclosure is supplied with open top and bottom cable-entry areas, allowing suitable C-flange or ring-flange cable-entry accessories to be selected for the installation.

Reliable Manual Change-Over Switching
The ABB OT160KLAA3C provides a dedicated manual means of selecting between two electrical supplies or circuits. Its I-O-II operating sequence provides two source positions separated by an OFF position, making the switch suitable for applications such as mains-to-generator transfer, alternative supply selection and other manually controlled change-over arrangements where appropriately designed.
The IP54 steel-sheet enclosure provides robust protection for the switching assembly, while the front-operated pistol handle makes the selected position clearly visible. Open top and bottom cable-entry areas provide flexibility for substantial incoming and outgoing conductors, with suitable cable-entry flanges selected separately to match the installation.
Typical Applications
- Manual mains-to-generator change-over systems.
- Alternative electrical supply selection.
- Industrial three-phase distribution systems.
- Commercial low-voltage power distribution.
- Manufacturing and process installations.
- Backup and standby supply arrangements.
- Manual transfer between two suitable electrical circuits.
