Why Choose the ABB OT400DLAA3C Enclosed Changeover Switch?
The ABB OT400DLAA3C, ABB order number 1SCA022280R2950, is a heavy-duty 400 A 3-pole enclosed changeover switch designed for reliable switching between two electrical supplies in demanding industrial low-voltage installations. As part of the proven ABB OT enclosed changeover switch range and product group 311019-Metal Enclosed (Loadbreak), it combines high-current switching capability with a robust steel-sheet enclosure.
This enclosed changeover switch provides 3-pole switching with manual I-O-II operation, allowing a connected load to be selected between two supplies with an OFF position between them. Its IP54 protection rating provides protection for industrial environments, while the black pistol-type operating handle gives operators clear visual indication of the selected switching position.
With a rated operational current of 400 A for AC-22A applications up to 690 V and 400 A for AC-23A applications up to 415 V, the OT400DLAA3C is designed for substantial industrial loads. The enclosure measures approximately 400 × 800 × 230 mm and is supplied with open top and bottom cable-entry sides, allowing suitable cable-entry flanges to be selected separately for the installation.
