Why Choose the ABB OT800KLAA4C 800 A Enclosed Change-Over Switch?
The ABB OT800KLAA4C, order number 1SCA022580R4340, is a heavy-duty 800 A, 4-pole steel sheet enclosed change-over switch designed for manual transfer between two electrical supplies in high-current industrial installations. Part of ABB’s metal-enclosed load-break range, it combines high-capacity change-over switching with a robust IP54 steel enclosure.
The OT800KLAA4C is front operated with a clear I-O-II switching sequence, providing Source I, OFF and Source II positions. Its four-pole configuration enables four conductors to be switched together, making it particularly suitable for three-phase systems where switched-neutral or complete four-pole source transfer is required.
The enclosure is supplied with open top and bottom cable-entry sides, allowing suitable C-flange or ring-flange entries to be selected separately for the installation. With operational current ratings of 720 A AC-22A up to 690 V and 720 A AC-23A up to 415 V, the OT800KLAA4C provides a substantial manual change-over solution for industrial power distribution and standby supply systems.

Reliable Four-Pole High-Current Supply Change-Over
Change-over switches provide a controlled method of selecting between two electrical supplies while incorporating an intermediate OFF position. The ABB OT800KLAA4C combines an 800 A-class four-pole change-over mechanism, front operation and protective steel enclosure into a complete assembly for demanding industrial power systems.
Its four-pole arrangement is particularly useful where all four conductors need to be transferred between sources. The open top and bottom entry arrangement also provides flexibility for large incoming and outgoing conductors, allowing the appropriate cable-entry hardware to be selected for each installation.
Typical Applications
- Mains-to-generator change-over systems.
- Normal and alternative power-source selection.
- Three-phase systems requiring four-pole source switching.
- Industrial standby and backup power systems.
- High-current industrial distribution systems.
- Manufacturing and production facilities.
- Critical plant and infrastructure power systems.
- Manual source-selection and isolation applications.
