1SCA022474R7150 ABB 315A 4-Pole Steel Enclosed Change-Over Switch

Why Choose the ABB OT315KLAA4C 315A 4-Pole Enclosed Change-Over Switch?

The ABB OT315KLAA4C is a heavy-duty 315 A 4-pole steel-sheet enclosed change-over switch designed for dependable switching between two electrical supplies or circuits in industrial power distribution applications. Identified by ABB order code 1SCA022474R7150, it belongs to ABB product group 311019 – Metal Enclosed (Loadbreak) and combines ABB OT change-over switching technology with a robust steel-sheet enclosure.

Designed for high-current change-over applications, the OT315KLAA4C uses an I-O-II operating arrangement, providing two switched positions with a central OFF position. The enclosure is supplied with open cable entries at both the top and bottom, allowing C-flanges or ring-flange cable-entry components to be selected separately according to the installation requirements.

With a rated operational current of 315 A and a 4-pole configuration, the OT315KLAA4C is suitable for substantial low-voltage circuits where four conductors must be changed over simultaneously. Its steel-sheet enclosure, black pistol-type handle and integrated PE terminals provide a practical solution for industrial supply selection, transfer and change-over duties.
