Mebay ATS320AC ATS Controller is the automatic transfer switch: it senses the mains failure, starts the set, transfers the load and returns it once the mains is stable.
Most ATS failures are not in the switch but in its logic: a drifting mains-sensing relay, an open control fuse or a cut signal wire. The symptom is a set that starts but never takes load.

How to verify before ordering
- Match the number of poles, the rated current and the switching type (contactor or motorised breaker).
- Check the ATS control voltage: 110 V, 220 V or 24 V depending on the panel it goes into.
- Confirm whether neutral is switched. On installations with a distributed neutral this is mandatory.
- The reference shown on this listing is ATS320; cross-check it against the one stamped on the removed part.
Frequently asked questions
The set starts but the load is not transferred. What do I check?
The signal first: mains-sensing relay, control fuse and the wiring between ATS and set. Then the interlock: if the mains contactor does not release, the generator contactor will not close, by design.
Can I fit an ATS of another brand?
Yes, as long as control voltage and logic are compatible with the set panel. With a controller-based set, the ATS must accept that controller transfer signal.
