OT1600E13CP ABB 1600 A 4-Pole Manual Changeover Switch

Why Choose the ABB OT1600E13CP Manual Changeover Switch?

The ABB OT1600E13CP is a heavy-duty 1600 A four-pole manual changeover switch designed for high-current source selection in low-voltage power distribution systems. Part of ABB's OT changeover switch range, it provides dependable manual transfer between two electrical supplies in industrial, commercial and infrastructure installations.

The OT1600E13CP uses an I-0-II open-transition switching arrangement, providing a defined OFF position between the two connected sources. Its four-pole construction enables four conductors to be switched together, making it suitable for applications where all three phases and the neutral need to be transferred.

The switch is supplied with a black plastic IP65 I-0-II pistol-type handle, operating shaft and bolt set for cable connection. The handle can be padlocked in the 0 position, while door interlocking in the I and II positions supports controlled operation and isolation in demanding switchboard applications.

High-Current Manual Source Selection with Open Transition

Manual changeover switches provide a straightforward method of selecting between two power sources without requiring a motor operator or automatic transfer controller. The ABB OT1600E13CP uses an I-0-II open-transition arrangement so the connected source is disconnected before the alternative source is selected, helping maintain clear electrical separation during manual transfer.

With its 1600 A four-pole construction, high short-circuit withstand capability and supplied operating hardware, the OT1600E13CP is engineered for demanding source-selection duties. The padlockable handle and door-interlocking functionality further support safe operating procedures in industrial switchboards and high-current distribution assemblies.

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 electrical distribution.
• Three-phase systems requiring switched-neutral changeover.
• OEM switchgear and power distribution assemblies.
