Changeover and ATS planning for controlled power-source transfer.
A backup source is only useful when the relationship between sources is controlled. Changeover and ATS projects should define source type, phase, poles, load current, transfer method, interlocking and installation environment before a model is selected.
Choose this family for the right electrical problem.
The category name is only the starting point. A suitable version depends on the supply, connected load, installation method, protection objective and target market.
For systems where the operator intentionally selects between available sources and safe isolation remains essential.
For projects that require source monitoring and automatic switching according to defined logic.
For generator, inverter or other backup systems where poles, neutral treatment, interlocking and control behaviour must match the installation.

Frequently asked questions
Short answers to common sourcing and specification questions. Final suitability still depends on the exact market, load and product configuration.
What information is needed to select a changeover switch or ATS?
Provide source types, nominal voltage, phase, required poles, neutral treatment, continuous load current, load type, manual or automatic transfer logic, installation method and quantity.
Is current rating alone enough to select an ATS?
No. The actual load duty, phase configuration, poles, source architecture, switching method and control logic also affect suitability.
Can an ATS be used between grid and inverter power?
Potentially, if the source voltages, waveform, neutral arrangement, switching method and transfer logic are compatible with the intended system.
What is the difference between manual changeover and automatic transfer?
Manual changeover requires an operator to select the source. An ATS monitors defined source conditions and performs transfer according to its control logic.
