Hiutgowt WFQ4-100/4P 100 A 4-Pole Transfer Switch

The Hiutgowt WFQ4-100/4P is a DIN-rail transfer switch listing automatic and manual operation for switching between power sources. Its stated 100 A rating and four-pole configuration make it a candidate for appropriately designed backup-power installations, but the listing’s 33 kW claim and voltage descriptions should be checked against the intended electrical system before purchase.

At a glance

Lists automatic and manual transfer operation, allowing automatic switching with a manual operating option.
DIN-rail mounting and listed dimensions provide useful checks for panel fit.
Four-pole configuration is presented for switching three phases and neutral, according to the listing.
The manufacturer claims transfer in less than 50 milliseconds and voltage monitoring below 103V or above 127V. These are listing claims, not verified performance.

What to know before buying

Listing details to confirm

Listing details are inconsistent: the title describes AC110V and 4P at 50/60Hz, a details field says 4-way, and the feature text describes a 110V three-phase system while claiming 33 kW. Confirm phase arrangement, pole/circuit terminology, voltage, current rating, and applicable system capacity with a qualified electrician before selection. The claimed voltage thresholds and sub-50-millisecond transfer are also manufacturer statements, not confirmed performance.

Aggregate ratings lean positive overall, but include a small one-star portion as well. Without written customer feedback, these ratings cannot explain what buyers liked or what prompted lower scores. They provide limited context and do not establish the switch’s electrical suitability or validate its performance claims.

Frequently asked questions

Can this switch operate automatically and manually?

The listing specifies both Manual and Automatic operation. It also describes manual override, but does not provide independently verified operating details.

What electrical system is it intended for?

The listing identifies 110 volts_of_alternating_current and calls the switch 4P, while feature text describes a 110V three-phase system. These details do not establish suitability for a particular installation, so confirm the system and ratings with a qualified electrician.

What is included in the listed package?

The manufacturer contents list specifies one 4P 100A AC110V ATS, four accessory cables, and one instruction manual. Check the selected listing to confirm the package.
