OT1000E22CP ABB 1000 A 4-Pole Manual Changeover Switch

Why Choose the ABB OT1000E22CP Manual Changeover Switch?

The ABB OT1000E22CP is a heavy-duty 1000 A four-pole manual changeover switch designed for dependable source selection in high-current low-voltage power distribution systems. Part of ABB's OT changeover switch range, it provides a robust mechanical solution for transferring electrical loads between two supplies.

The OT1000E22CP uses an open-transition I-0-II switching arrangement with a stable OFF position, ensuring one source is disconnected before the alternative source is connected. Its four-pole construction is suitable for systems where four conductors must be switched together, including three-phase installations requiring switched-neutral operation.

Rated at 1000 A, the OT1000E22CP provides AC-21A and AC-22A switching at 1000 A up to 415 V, together with an AC-23A rating of 1000 A / 560 kW at 400–415 V. It is supplied with a black plastic IP65 I-0-II pistol handle, operating shaft and bolt set for cable connection, providing a comprehensive manual changeover solution for demanding switchboard applications.

High-Current Manual Source Selection with Open Transition

Manual changeover switches provide a straightforward method of selecting between two electrical supplies without requiring a motor operator or automatic transfer controller. The ABB OT1000E22CP uses an I-0-II operating sequence with a stable OFF position, providing break-before-make transfer so that the connected source is isolated before the alternative source is selected.

With its 1000 A four-pole construction, robust AC-23A switching capability and supplied operating hardware, the OT1000E22CP is designed for demanding distribution applications. Its padlockable handle and door-interlocking functionality also support controlled operation and isolation within industrial and commercial switchboards.

Typical Applications

• Mains and generator manual changeover systems.
• Dual-supply low-voltage distribution systems.
• High-current industrial switchboards.
• Standby power source selection.
• Commercial and infrastructure power distribution.
• Three-phase systems requiring switched-neutral changeover.
• OEM switchgear and power distribution assemblies.
