OT1600E03N3 ABB 1600 A 3P+N Switch Disconnector

Why Choose the ABB OT1600E03N3 Switch Disconnector?

The ABB OT1600E03N3 is a heavy-duty 1600 A 3P+N switch disconnector designed for dependable switching and electrical isolation in high-current industrial power distribution systems. As part of the ABB OT switch-disconnector series, it provides robust manual isolation for switchboards, distribution panels and demanding low-voltage installations.

This model combines three switched poles with an integrated removable neutral link, providing a 3P+N arrangement for three-phase distribution systems incorporating a neutral conductor. The switch is front operated and base mounted, with the operating mechanism positioned at the end of the switch for practical integration into industrial switchgear assemblies.

With a conventional free-air thermal current of 1600 A, the OT1600E03N3 is designed for substantial electrical loads, while the integrated neutral is rated at 1250 A. The switch is supplied without an operating handle and shaft, allowing suitable operating accessories to be selected separately for the installation.

Reliable High-Current Switching and Isolation

Switch disconnectors provide manual load switching together with dependable electrical isolation, allowing circuits and equipment to be disconnected from their supply during maintenance, servicing and operational procedures. High-current industrial installations require robust switching devices capable of carrying substantial continuous loads while providing reliable isolation performance.

The ABB OT1600E03N3 combines a 1600 A main-pole rating with an integrated neutral arrangement, making it particularly suitable for three-phase distribution systems where a neutral connection must be incorporated into the switching assembly. Its high short-circuit withstand capability and robust base-mounted construction support demanding industrial switchboard applications.

Typical Applications

• Industrial low-voltage switchboards.
• High-current electrical distribution systems.
• Main and local electrical isolation.
• Three-phase distribution systems incorporating a neutral conductor.
• Manufacturing and process plant switchgear.
• Commercial and industrial power distribution panels.
• Industrial control and electrical infrastructure assemblies.
