Hiutgowt 2P 100A 220V Automatic Transfer Switch

Hiutgowt 2P 100A 220V is a DIN-rail automatic/manual transfer switch listed for changing between utility and backup power sources. Its claimed 220V configuration needs careful checking: another feature description instead refers to monitoring a 110V grid, so confirm the required voltage and electrical ratings before purchase or installation.

What to know before buying

Listing details to confirm

Listing details are contradictory or unconfirmed: the title and model specify 220V, while the voltage-monitoring feature describes a 110V grid and 90V/140V thresholds. The 100A claim appears alongside a 22000-watt figure, and the listed 220V rating conflicts with feature text referring to 110V. Verify the intended supply voltage, switching ratings, and suitability with a qualified electrician before use. The advertised 0.05-second transfer and voltage-protection performance are manufacturer claims, not verified results.

Who is it for?

A good fit for

Buyers designing a DIN-rail backup-power setup who need manual and automatic source selection and can confirm the switch matches their electrical system.

Less suited to

Buyers who need an established 110V or 220V rating without resolving the conflicting listing claims.
Anyone seeking independently verified transfer speed, voltage protection, or electrical performance.

Aggregate ratings lean favorable, with many five-star ratings, but a notable one-star share makes the overall picture less uniform. The rating data provides no specific reasons for either positive or negative experiences, so it cannot confirm switching performance or resolve the listing's voltage discrepancy. Buyers should prioritize verifying electrical compatibility.

Frequently asked questions

Can this switch be used on a 110V system?

The listing is inconsistent. Its title and model say 220V, but a feature description discusses a 110V grid and voltage thresholds. Confirm the actual unit rating and compatibility before purchase.

Does it support manual and automatic switching?

Both manual and automatic operation are listed. The manufacturer describes automatic source switching and manual selection, but the performance claims have not been independently verified.

How does it mount?

The listing specifies DIN-rail mounting and gives dimensions of 4.24 x 2.99 x 3.94 inches. Confirm that your enclosure and rail arrangement fit.
