Why Choose the ABB OT315E03C 315 A 3-Pole Manual Changeover Switch?
The ABB OT315E03C is a robust 315 A 3-pole manual changeover switch designed for dependable source selection in low-voltage power distribution systems. Part of the ABB OT Changeover Switches range, it provides a practical solution for industrial switchboards, distribution panels and power systems requiring manual transfer between two electrical supplies.
This model uses an I-O-II open-transition operating sequence, providing a defined OFF position between the two source positions. Its three-pole configuration is suitable for three-phase circuits, while the operating mechanism is positioned at the left-hand end of the switch.
Rated at 315 A, the OT315E03C provides 315 A AC-22A and AC-23A switching capability at 415 V, with an AC-23A operational power rating of 160 kW at 400 V. This version is supplied without a handle and shaft, allowing suitable ABB operating accessories to be selected separately for the installation.

Reliable Three-Phase Power Source Changeover
Manual changeover switches provide a controlled method of selecting between two electrical supplies. The ABB OT315E03C uses an I-O-II open-transition arrangement so that the switching sequence passes through a defined OFF position when transferring the circuit from one source to the other.
Its 315 A rating, three-pole construction and strong AC-23A switching performance make the OT315E03C suitable for demanding three-phase power distribution applications. The separately selected handle and shaft provide installation flexibility for panel builders and switchboard manufacturers.
Typical Applications
- Main and alternative power supply changeover systems.
- Generator and mains source-selection systems.
- Industrial low-voltage distribution switchboards.
- Three-phase electrical distribution panels.
- Industrial machinery and plant power systems.
- Commercial and infrastructure electrical installations.
