Why Choose the ABB OT1250E03DDP 6-Pole Switch Disconnector?
The ABB OT1250E03DDP is a heavy-duty 1250 A six-pole switch disconnector designed for reliable manual isolation and switching in high-current industrial electrical distribution systems. As part of the ABB OT switch-disconnector series, it combines high electrical performance with a robust, compact construction suitable for demanding switchboard and power distribution applications.
This IEC switch disconnector is front operated and base mounted, with its six-pole arrangement implemented as two switching sections operated sequentially through a common mechanism. The operating handle has three positions, O – I – I+II, with only one switching section operated at a time as the mechanism progresses through its operating sequence.
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 OT1250E03DDP is engineered for substantial industrial loads. It is supplied with a black plastic pistol handle, handle extension and shaft, providing a complete manual operating arrangement for installation in electrical panels and switchboards.

Reliable High-Current Switching and Isolation
Switch disconnectors provide manual switching together with dependable circuit isolation, allowing electrical equipment to be disconnected from its supply for maintenance, servicing and operational control. High-current industrial installations require switching devices capable of carrying substantial continuous loads while providing clear and dependable mechanical operation.
The ABB OT1250E03DDP is designed for these demanding applications with a 1250 A rating and six-pole arrangement. Its staged operating mechanism, adjustable shaft and padlockable IP65 handle make it well suited to switchboards where reliable operation, secure isolation and practical installation are important.
Typical Applications
- Industrial low-voltage switchboards.
- High-current electrical distribution systems.
- Main and local electrical isolation.
- Manufacturing and process plant switchgear.
- Power distribution panels and control assemblies.
- Industrial machinery and infrastructure electrical systems.
