The ABB OT800KLAA3C, order number 1SCA022389R8310, is a heavy-duty 800 A, 3-pole steel enclosed change-over switch designed for controlled transfer between two electrical supplies in high-current industrial installations. Part of ABB’s metal-enclosed load-break switch range, it combines dependable change-over switching with a robust IP54 steel sheet enclosure.
The OT800KLAA3C is a front-operated change-over assembly with an I-O-II operating sequence, providing clearly defined Source I, OFF and Source II positions. It is supplied with a black pistol-type operating handle together with neutral and protective-earth terminals, creating a practical enclosed solution for industrial supply transfer, generator change-over and alternative-source applications.
With an authoritative equipment rating of 800 A and a 3-pole configuration, the OT800KLAA3C is designed for substantial three-phase loads. Its cable-entry sides are supplied open, allowing suitable C-flange or ring-flange entry components to be selected separately according to the cabling requirements of the installation.
Change-over switches provide a controlled means of selecting between two electrical supplies while incorporating an intermediate OFF position. The ABB OT800KLAA3C combines high-current change-over switching, front operation and a protective steel enclosure into a complete assembly suitable for substantial three-phase industrial power systems.
The I-O-II operating arrangement makes the switch suitable for applications involving normal and alternative supplies, including mains and generator systems. Its open top and bottom cable-entry arrangement allows the enclosure to be configured with appropriate flange accessories for large incoming and outgoing conductors, providing flexibility in high-current installations.
