ABB 315A 3-Pole Steel Enclosed Changeover Switch – 1SCA022280R2790
The ABB 1SCA022280R2790 is a 315 A, three-pole steel enclosed changeover switch designed for controlled switching between two electrical supplies or circuits in suitable low-voltage installations. Classified within ABB's Metal Enclosed (Loadbreak) product group, this robust switching assembly is intended for industrial and commercial electrical distribution applications.
Its 315 A current rating, three-pole configuration and steel enclosure make it a practical solution for electrical systems requiring a dedicated manual changeover point. The enclosed arrangement helps protect the switching mechanism while providing a convenient location for operation and maintenance.
Designed for appropriate three-phase installations, the ABB enclosed changeover switch supports planned source selection, equipment supply transfer and electrical distribution arrangements where two supply paths must be managed through a common switching point.

Controlled Changeover Between Electrical Supplies
The ABB 315 A three-pole enclosed changeover switch is intended for electrical installations where a load or distribution circuit must be connected to one of two available supply paths. Changeover switching can support mains-to-alternative-supply arrangements, maintenance supply selection and other engineered distribution systems.
The three-pole construction provides switching of three conductors in a suitable three-phase circuit. Where a neutral conductor is present, its treatment must be determined separately according to the electrical system design, earthing arrangement and applicable installation requirements.
The 315 A rating provides a key selection parameter, but final suitability must also be checked against the manufacturer's applicable operational voltage, utilisation category, making and breaking capacities, and short-circuit coordination requirements.
For generator or dual-supply applications, the overall installation must include appropriate source interlocking, protection and operating procedures. The changeover switch itself should not be assumed to provide automatic transfer, synchronisation or overload protection.
Durable Steel Enclosed Construction
The steel enclosure provides a robust housing for the changeover switching assembly and is suited to industrial and commercial electrical installations where mechanical protection and orderly equipment arrangement are important.
The enclosure must be installed in accordance with ABB's applicable mounting, cable termination, protective earthing and environmental requirements. Its precise ingress protection rating, dimensions and cable-entry configuration should be confirmed for the supplied assembly before installation.
Typical Applications
- Manual mains and alternative supply changeover.
- Industrial three-phase electrical distribution.
- Commercial building supply selection.
- Generator changeover arrangements with suitable system protection.
- Maintenance and operational supply transfer points.
- Industrial plant electrical infrastructure.
- Manufacturing and processing facilities.
- Electrical distribution board installations.
- Panel building and power distribution projects.
- Applications requiring a 315 A three-pole steel enclosed changeover switch.
