Why Choose the ABB OT1250KLAA3B 1250A 3P IP54 Enclosed Switch-Disconnector?
The ABB OT1250KLAA3B is a heavy-duty 1250 A three-pole steel-sheet enclosed switch-disconnector designed for dependable load switching and electrical isolation in high-current low-voltage power systems. Part of the ABB OT switch-disconnector range and ABB's 311019-Metal Enclosed (Loadbreak) product group, it combines substantial switching capacity with robust IP54 enclosed construction.
Designed for industrial distribution, large machinery, plant supplies and high-current feeder applications, the OT1250KLAA3B provides a clearly operated disconnecting point for three-phase electrical circuits. The assembly uses a front-operated ABB OT switch-disconnector within a steel-sheet enclosure and includes a black pistol-type operating handle with I-O / ON-OFF indication.
The OT1250KLAA3B has a rated operational current of 1250 A for AC-22A duty and 1250 A for AC-23A duty at up to 415 V. The enclosure is supplied with open top and bottom cable-entry areas, allowing suitable C-flange or ring-flange cable-entry components to be selected separately for the installation.
