Socomec ATyS Bypass: enclosed transfer switch, 40 to 3200 A

ATyS Bypass packages the ATyS transfer switching range into a floor-standing enclosure with a manual bypass path, spanning the same broad 40 to 3200 A range as the rest of the ATyS family. We have not checked a datasheet for this specific enclosed line; the range comes from our internal product list.

No PDF was checked for this enclosed bypass line; the 40–3200 A range comes from our internal product list only. Confirm the exact rating and enclosure dimensions with Socomec before quoting. An en dash means the manufacturer does not publish that value in the source we hold; we do not fill it in with an estimate. Confirm every figure against the current manufacturer document before it is written into a contract.

The references we quote in this family are ATyS Bypass. Send us the load, the phase and the transfer requirement, and we will confirm availability and lead time.

Which one should you choose?

The bypass path is the entire point of this variant

A bypass path lets maintenance staff route power around the transfer switch mechanism itself without interrupting the load, which matters for a facility that cannot tolerate downtime even for switch servicing. If bypass capability is not needed, a standard enclosed ATyS reference is likely simpler and cheaper.

Verify the exact rating with Socomec before it goes into a proposal

Because we have not confirmed a specific datasheet for this line, treat the 40-3200 A figure as the general ATyS family range rather than a guaranteed rating for the bypass-enclosed variant specifically. Ask us to confirm the exact model and rating with Socomec for the load in question.

The physical selector switches shown on the enclosure map directly to the bypass logic

The enclosure’s front panel carries clearly labelled selector switches for normal versus bypass operation and for the two incoming sources, which means the operating state is visible at a glance rather than requiring a separate status screen to interpret. This matters for a maintenance team working under time pressure during a switch service.

Made-in-France manufacturing is a genuine sourcing detail for some public-sector tenders

The enclosure is manufactured in France, which can matter directly for a public-sector or defence-adjacent tender with local-content or EU-manufacturing requirements. Confirm whether the customer’s procurement rules care about country of manufacture before assuming it is irrelevant.

Where it fits, and where it does not

Fits a facility that specifically needs to maintain the transfer switch without interrupting the load. Does not fit a project where a standard enclosed ATyS reference without bypass is acceptable; that is likely the simpler, cheaper choice.

What we need in order to quote it

  • Load current within the 40 to 3200 A range
  • Confirmation of the exact rating with Socomec before quoting
  • Enclosure dimensions available at the installation site
  • Whether bypass maintenance capability is a genuine requirement
