OT1600E04P ABB 1600 A 4-Pole Isolator Switch

Why Choose the ABB OT1600E04P 4-Pole Isolator Switch?

The ABB OT1600E04P is a heavy-duty 1600 A four-pole isolator switch / switch disconnector designed for dependable switching and electrical isolation in high-current industrial power distribution systems. As part of the advanced ABB OT switch-disconnector series, it provides robust manual isolation for switchboards, distribution panels and demanding low-voltage installations.

This front-operated, base-mounted switch features four simultaneously switched poles, making it suitable for three-phase systems where the neutral conductor also requires switching. Its mechanism is positioned at the end of the switch, while the fourth pole is located on the left-hand side for a compact and practical switchboard arrangement.

With an open-air thermal current of 1600 A, rated operational currents of 1600 A AC-22A and 1250 A AC-23A at 400–415 V, and a 50 kA short-time withstand current for 1 s, the OT1600E04P is engineered for demanding industrial distribution duties. It is supplied with a black IP65 pistol handle, adjustable operating shaft and terminal bolt kit for straightforward integration into electrical assemblies.
