1SCA022341R1380 ABB 400 A 4-Pole Steel Enclosed Switch Disconnector IP54

Why Choose the ABB OT400DLAA4B Enclosed Switch Disconnector?

The ABB OT400DLAA4B, ABB order number 1SCA022341R1380, is a heavy-duty 400 A 4-pole enclosed switch disconnector designed for reliable load-break switching and electrical isolation in demanding industrial low-voltage installations. As part of the ABB OT enclosed switch-disconnector range and product group 311019-Metal Enclosed (Loadbreak), it combines high-current switching capability with a robust steel-sheet enclosure.

This enclosed switch disconnector provides 4-pole switching with manual I-O / ON-OFF operation, making it suitable for three-phase and neutral electrical systems where all four conductors require switching. Its IP54 protection rating provides protection for industrial environments, while the pistol-type black operating handle provides clear local control and isolation.

With rated operational currents of 400 A AC-22A up to 690 V and 400 A AC-23A up to 415 V, the OT400DLAA4B is designed for substantial industrial loads. The steel-sheet enclosure measures approximately 800 × 400 × 230 mm and is supplied with open top and bottom cable-entry sides, allowing suitable C-flanges or ring-flanges to be selected separately for the installation.
