Why Choose the ABB OT315E12CP 315 A 3-Pole Manual Changeover Switch?
The ABB OT315E12CP is a heavy-duty 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 reliable manual transfer between two electrical supplies for industrial switchboards, distribution panels and alternative power systems.
The OT315E12CP uses an I-O-II open-transition operating sequence with a stable OFF position, ensuring that one source is disconnected before the alternative source is selected. Its three-pole construction is suitable for three-phase circuits, while the operating mechanism is positioned between the poles.
Rated at 315 A, the OT315E12CP provides 315 A AC-21A, AC-22A and AC-23A switching capability at 380–415 V, with an AC-23A operational power rating of 160 kW at 400 V. The CP configuration is supplied with a black plastic IP65 I-O-II pistol-type handle, operating shaft and bolt set for cable connections.

Reliable Three-Phase Power Source Changeover
Manual changeover switches provide a controlled method of selecting between two electrical supplies. The ABB OT315E12CP uses an I-O-II open-transition arrangement with a stable OFF position, ensuring that the load is disconnected from one source before connection to the alternative source.
The combination of a 315 A rating, three-pole construction and mechanism positioned between the poles makes the OT315E12CP a practical solution for demanding three-phase source-selection systems. Its supplied operating handle, shaft and connection hardware also simplify integration into suitably designed switchboards and electrical panels.
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.
