Why Choose the ABB OT1250E30W4 1250 A 3-Pole Switch-Disconnector?
The ABB OT1250E30W4 is a heavy-duty 1250 A 3-pole switch-disconnector designed for reliable isolation and switching of high-current low-voltage electrical circuits. As part of the established ABB OT switch-disconnector series, it is engineered for industrial power distribution, switchboards and electrical installations where dependable circuit isolation is essential.
This OT1250 variant features a 140 mm phase distance, identified by the W4 configuration, providing increased spacing between the power poles for suitable switchboard and busbar arrangements. The E30 configuration provides the specified three-pole switching arrangement, while this version is supplied without handle and shaft, allowing the appropriate operating accessories to be selected for the installation.
With a rated current of 1250 A and a 3-pole configuration, the OT1250E30W4 provides a robust isolation solution for demanding three-phase electrical distribution systems. Its high-current construction and wide phase spacing make it particularly suitable for industrial switchgear, distribution boards and OEM power assemblies.

Reliable High-Current Electrical Isolation
Switch-disconnectors provide a defined means of switching and isolating electrical circuits so equipment can be safely separated from its power source when required. The ABB OT1250E30W4 combines a high 1250 A current rating with a robust three-pole arrangement for demanding industrial power distribution applications.
The 140 mm phase distance provides increased spacing between poles and supports switchboard designs requiring wider conductor or busbar separation. Because this OT1250E30W4 configuration is supplied without a handle and shaft, suitable operating accessories can be selected according to the enclosure, panel depth and operating arrangement of the finished installation.
Typical Applications
- Industrial low-voltage switchboards and distribution panels.
- Main electrical isolation for industrial machinery.
- High-current three-phase distribution systems.
- Power distribution and control assemblies.
- Industrial plant electrical infrastructure.
- OEM switchgear and panel-building applications.
