OT1600E04 ABB 1600 A 4-Pole Switch-Disconnector

Why Choose the ABB 1SCA022860R6660 OT1600E04 Switch-Disconnector?

The ABB 1SCA022860R6660, order code OT1600E04, is a heavy-duty 1600 A, 4-pole switch-disconnector designed for dependable high-current switching and electrical isolation in industrial power distribution systems. As part of the ABB 311027-OT Switches product group, it belongs to ABB's OT range of manually operated switch-disconnectors for switchboards, distribution assemblies and demanding industrial equipment.

The OT1600E04 is a front-operated, base-mounted 4-pole switch-disconnector. This specific version is supplied without an operating handle or shaft, allowing suitable ABB operating accessories to be selected separately according to enclosure depth and switchboard design. A terminal bolt kit is included with the switch for installation.

With a conventional free-air thermal current of 1600 A and rated operational currents of 1600 A for AC-21A, AC-22A and AC-23A duties at 380–415 V, the OT1600E04 is engineered for substantial industrial loads. It supports operational voltages up to 1000 V, provides 710 kW AC-23A switching capability at 380–415 V and has a 50 kA short-time withstand current.

High-Current Four-Pole Industrial Isolation

Switch-disconnectors provide a dedicated means of manually switching and isolating electrical circuits from their power source. The ABB OT1600E04 combines a substantial 1600 A current rating with four-pole switching, making it suitable for industrial distribution systems where four conductors must be switched and isolated together.

Because this OT1600E04 version is supplied without a handle and shaft, switchboard builders can select compatible ABB operating accessories to suit the required enclosure depth and installation arrangement. Its 50 kA short-time withstand capability, 1000 V maximum operational voltage and strong AC-23A performance make it a robust solution for demanding high-current switching and isolation duties.

Typical Applications

• High-current industrial power distribution.
• Main and sub-main electrical isolation.
• Four-pole switchboard isolation.
• Industrial switchboards and distribution assemblies.
• Large machinery and production equipment.
• High-power motor and industrial load switching.
• Manufacturing and process installations.
• Power generation and infrastructure systems.
