wading through catalogues in original FR (not FR translations of Chinglish) would probably yield the right term, but I've got no time for that. At least Asker knows now exactly what to look for.

No, it's more accurately "sous courant" — whence the problem for rendering that properly in FR.
I think probably "sous charge" would do the trick?

basically "brancher ou débrancher sous tension" / "capable d’être branché ou débranché sous tension"?

OTOH not sure what would be the usual technical term.

Partly right, but one important point needs clarifying: 'under load' doesn't merely mean 'when voltage is present', but more specifically, 'when current is flowing' — that's what the 'load' is'.
Some connectors might be rated for carrying quite a high load current, BUT would not be able to withstand being plugged in or unplugged with the current flowing (or about to flow) — this would lead to e.g. the arcing Daryo describes, which might damage the connector. This is why they will often have ratings that include a 'working current' and also a much lower value for 'on-load make/break current'; these connectors are well designed and of superior quality if both ratings are the same.

get the right meaning

connectors are rated for “Make or Break” under load
=
you can both connect and disconnect the cable (/the circuit) when on one or both of the ends being connected are "under load" / there is voltage in them. IOW you don't have to worry if the cable is under tension or not when you want to plug or unplug it.

Some connectors being rated for “Make or Break” under load implies that some other are not. Not all all connectors can be plugged or unplugged if there is a voltage - in some cases unplugging when there is still a voltage can be extremely unwise (sparks start flying everywhere)

Can't see how would that have anything to do with "résistance" ....

Also, agree with Tony that the whole of

rated for make or break under load

should be the question.

We tend to look at this in a slightly different way in FR, so you can't translate 'make or break' in isolation: you need to consider the expression as a whole.
