Why Choose the ABB OT315E03CP 315 A 3-Pole Manual Changeover Switch?
The ABB OT315E03CP is a robust and reliable 315 A, 3-pole manual changeover switch designed for controlled switching between two electrical power sources in industrial and commercial low-voltage distribution systems. As part of the ABB OT manual changeover switch series, it provides a dependable solution for mains-to-generator changeover, alternative power supply selection and industrial electrical distribution applications.
This switch features a three-position I-0-II operating mechanism, allowing operators to select between two electrical supplies with a stable intermediate OFF position. Its open-transition, break-before-make switching principle disconnects the active source before connecting the alternative source, preventing simultaneous connection of the two supplies during normal changeover operation.
With a rated operational current of 315 A, a 3-pole configuration and a rated operational voltage of up to 1000 V AC, the OT315E03CP is suitable for industrial switchboards and power distribution panels. The switch is supplied with a black plastic IP65 pistol-type operating handle, shaft and cable connection bolt set, enabling convenient manual operation from a compatible electrical enclosure.

Reliable Manual Power Source Changeover for Industrial Distribution Systems
Manual changeover switches such as the ABB OT315E03CP allow electrical installations to transfer between two alternative power sources through a mechanically operated switching mechanism. In a typical mains-to-generator arrangement, position I connects the primary supply, position 0 disconnects both supplies and position II connects the alternative supply. The open-transition design provides a defined break-before-make switching sequence to prevent the two sources from being connected simultaneously during normal operation.
The ABB OT315E03CP is designed for industrial electrical engineers, switchboard manufacturers and power distribution specialists requiring dependable manual source selection. Its three-pole construction enables simultaneous switching of three phase conductors, while its mechanically interlocked I-0-II arrangement provides a clear operating sequence. The included pistol-type handle and shaft enable convenient operation from a compatible switchboard enclosure.
The switch is suitable for integration into generator changeover panels, industrial distribution boards and alternative supply installations. As a manually operated device, it requires an operator to perform the changeover and does not provide automatic mains failure detection or automatic transfer functionality. Suitable upstream protection, conductor sizing and installation arrangements must be selected according to the electrical system requirements.
Typical Applications
- Manual mains-to-generator changeover installations.
- Industrial electrical distribution switchboards.
- Alternative power source selection in commercial buildings.
- Three-phase power distribution systems.
- Industrial manufacturing plants and production facilities.
- Manual switching between two compatible electrical supplies.
- Generator connection and backup power distribution panels.
- Industrial infrastructure and utility distribution assemblies.
- Electrical control and power distribution equipment.
- OEM switchgear assemblies and custom-built changeover panels.
