£8,125.18
The ABB OT1250KLAA4B is a heavy-duty 1250 A enclosed 4-pole switch-disconnector designed for reliable load switching and electrical isolation in industrial and commercial low-voltage distribution systems. Identified by ABB order number 1SCA022437R9840, it belongs to ABB's metal-enclosed load-break switch product group and combines high-current switching capability with a robust steel-sheet enclosure.
Designed for installations requiring dependable manual isolation of high-current circuits, the OT1250KLAA4B incorporates ABB OT switch-disconnector technology within a protective IP54 steel-sheet enclosure. Its enclosed construction provides protection against dust and water ingress while providing a practical switching solution for industrial electrical distribution and machinery installations.
With a rated operational current of 1250 A and a 4-pole configuration, the OT1250KLAA4B is suitable for switching three-phase systems where the neutral conductor must also be switched. The unit features front operation with a pistol-type black operating handle and is designed for straightforward integration into high-current electrical installations.
Switch-disconnectors provide manual load switching together with a defined means of isolating electrical equipment and distribution circuits. The ABB OT1250KLAA4B combines these functions with a substantial 1250 A current rating and 4-pole switching, making it particularly suitable for high-current three-phase systems where simultaneous switching of the neutral conductor is required.
The IP54 metal enclosure protects the switching equipment from environmental exposure, while the front-operated mechanism provides accessible manual control from outside the enclosure. This combination makes the OT1250KLAA4B suitable for industrial distribution, machinery supplies, infrastructure and other installations requiring robust high-current electrical isolation.
