Sezbaifles ATS G2R 4P 63A 110V AC Transfer Switch

The Sezbaifles ATS G2R 4P 63A 110V AC is a DIN-rail transfer switch listed for automatic or manual changeover between two power sources. Its stated four-pole, 63 A configuration and compact listed dimensions may suit installations planned around those specifications, but the supplied voltage detail needs careful confirmation before purchase.

At a glance

The listing describes switching between primary and backup supplies, with automatic return to the primary source when it is normal again.
Manual operation is also described, using a selector and handle to choose source I or II.
The listing claims changeover within 0.05 seconds and gives voltage thresholds for a 110V/50Hz configuration. Treat these as manufacturer claims, not verified performance.

What to know before buying

Listing details to confirm

The listing is inconsistent about material: the specifications say Copper, while the feature text says the housing is PA6 engineering plastic. Its 110V title and detail fields also sit alongside threshold values explicitly stated for 110V/50Hz and a broader 50/60Hz claim. Confirm the intended supply, pole and wiring configuration, and applicable operating thresholds before selecting or installing it. The 0.05-second changeover and CE claim are listing statements, not independently verified.

Who is it for?

A good fit for

Buyers planning a DIN-rail installation who need a listed automatic/manual selector between two power sources.
Installers evaluating a 63 A transfer switch for a configuration whose voltage and wiring requirements have been confirmed.

Less suited to

Anyone who needs independently verified transfer timing, certification or material information.
Buyers who cannot confirm that the listed voltage, pole arrangement and switching thresholds match their system.

Only aggregate ratings are supplied, with a mostly five-star distribution and some three-star ratings in a small sample. That is limited evidence and does not identify what customers liked or disliked. It cannot confirm the listed transfer timing, voltage compatibility, material or installation fit, so buyers should assess those details against their system.

Frequently asked questions

Can it switch automatically and manually?

The listing describes both modes. In automatic mode it says the switch transfers to the backup source when the primary is abnormal and returns when the primary is normal. Manual mode uses a handle to select source I or II.

What supply voltage should I plan around?

The title and specification fields state 110V, while the feature text includes thresholds specifically for 110V/50Hz and also claims 50/60Hz compatibility. Confirm that the actual supply and frequency match the intended configuration.

Is the listed changeover time independently verified?

No. The 0.05-second changeover time is a manufacturer listing claim, not an independently verified measurement.

What components are listed as included?

The stated contents list one G2R 63A 110V transfer switch and a manual. Check the selected listing for the package details.
