OT1600E12P ABB 1600 A 3-Pole Isolator Switch

Why Choose the ABB OT1600E12P 1600 A 3-Pole Isolator Switch?

The ABB OT1600E12P is a heavy-duty 1600 A 3-pole isolator switch / switch-disconnector designed for reliable switching and isolation of high-current low-voltage electrical circuits. As part of the proven ABB OT switch-disconnector series, it is engineered for industrial power distribution, switchboards and machinery installations requiring dependable three-phase circuit isolation.

The OT1600E12P uses ABB's mechanism-between-the-poles configuration and is designed for front operation and base mounting. This complete P-version is supplied with an OXP12X280 shaft, OHB274J12 black ON-OFF pistol handle and M12X60 terminal bolt kit, providing the principal operating accessories required for integration into a suitable electrical assembly.

With an open-air thermal current of 1600 A and a 3-pole configuration, the OT1600E12P is suitable for substantial industrial distribution duties. At 380–415 V AC it is rated at 1600 A for AC-21A and AC-22A duties and 1250 A for AC-23A duty, with an AC-23A operational power rating of 710 kW at 400–415 V AC.

Reliable High-Current Electrical Isolation

Switch-disconnectors provide a defined means of switching and electrically isolating circuits so downstream equipment can be separated from its power source for operation, servicing and maintenance. The ABB OT1600E12P combines a substantial 1600 A thermal-current rating with a robust three-pole mechanism for demanding industrial power distribution systems.

Its mechanism-between-the-poles arrangement provides a practical configuration for high-current switchboard designs, while the supplied shaft, pistol handle and terminal bolt kit support straightforward integration into suitable electrical assemblies. High AC-21A, AC-22A and AC-23A ratings make the OT1600E12P suitable for a broad range of industrial switching and isolation duties.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main electrical isolation for industrial plant and machinery.
• Three-phase power distribution systems.
• Main and sub-distribution electrical assemblies.
• Manufacturing and process plant electrical systems.
• OEM switchgear and high-current panel-building applications.
