Why Choose the ABB OT1250E03N3 Switch Disconnector?
The ABB OT1250E03N3 is a heavy-duty 1250 A 3P+N switch disconnector designed for reliable switching and isolation in high-current industrial electrical distribution systems. As part of the ABB OT switch-disconnector series, it provides robust manual isolation for switchboards, distribution panels and other demanding low-voltage installations.
This switch disconnector is front operated and base mounted, providing a practical configuration for installation inside electrical panels and switchgear assemblies. The OT1250E03N3 incorporates three switched poles together with a neutral arrangement, while its robust construction is engineered for dependable operation under substantial electrical loads.
With an open-air thermal current of 1250 A and rated operational currents of 1250 A AC-22A and 1250 A AC-23A at 400–415 V, the OT1250E03N3 is suitable for demanding industrial power distribution duties. The switch is supplied without the operating handle and shaft, allowing the appropriate operating accessories to be selected separately for the installation, while a terminal bolt kit is included.
