Why Choose the ABB OT315KTAA3T 315A EMC Enclosed Safety Switch?
The ABB OT315KTAA3T is a heavy-duty 315 A 3-pole EMC enclosed safety switch designed for dependable load switching and electrical isolation in industrial installations where electromagnetic compatibility is an important consideration. Identified by ABB order code 1SCA022398R9540, it belongs to ABB product group 311019 – Metal Enclosed (Loadbreak) and combines ABB OT switch-disconnector technology with an EMC-oriented steel-sheet enclosure.
Designed for high-current local isolation, the OT315KTAA3T features an IP54-rated grey steel-sheet enclosure with open cable entries at both the top and bottom. The open-entry arrangement allows suitable EMC cable-entry components and flanges to be selected for the installation, helping maintain effective shielding when used with appropriately shielded cables.
With a rated current of 315 A and a 3-pole configuration, the OT315KTAA3T is suitable for substantial three-phase loads. Its AC-23A motor switching ratings include 90 kW at 230 V, 160 kW at 400 V, 200 kW at 500 V and 250 kW at 690 V, making it suitable for large motors, drives, machinery and industrial power systems.
