English term or phrase: surge current
Devices with integrated overvoltage protection must be earthed.

surintensité
Explanation:
Asker's ST also uses the term 'switch-on current', so the translation must properly reflect the difference between the two phenomena.

'surge current' refers to abnormally high currents that flow - usually owing to a fault in the load or to some external cause (eg: a lightning strike) - some time after the power has been switched on.

Note that a surge is not necessarily 'transient' (a brief 'spike'); a slow but potentially damaging surge may occur, for example, if the system is slowly overloaded, eventually reaching the current level where the surge current limiter is triggered.

Principal source (with a friendly nod to Johannes): my 50-year-old recollections of operating rotating electrical machines (including 25kW / 16kV DC rotary transformers built in the 1920/30s).

Le courant d'enclenchement ou courant de choc


Explanation:
Le courant d'enclenchement ou courant d'appel est le nom donné à la surintensité transitoire qui se produit lors de la mise sous tension de certains récepteurs électriques. Ce courant, qui peut atteindre 10 à 50 fois le courant du régime établi, peut requérir d'utiliser des dispositifs de protection adaptés qui permettront le passage de ce courant élevé : fusibles temporisés ou disjoncteurs magnétothermiques spécifiques (accompagnement moteur, courbe D… dont le courant coupé par effet magnétique est très supérieur à celui coupé par effet thermique).

Inrush or Surge currents are a sudden current drawn by a device when first switched on. This surge in current will only last a few cycles of the input power until it returns to a normal state. Often caused by energy storage devices used with mutlifunction decoders.

disagree  Jennifer Levey: 'courant d'enclenchement' and 'courant d'appel' are valid answers for Asker's previous question (switch-on current). 'surge current' is a different concept and requires a different term. 'courant de choc' does not appear in your explanation.
40 mins
disagree  Tony M: I agree with Jennifer: this is a different kind of 'surge', not the same as the 'switch-on surge' discussed elsewhere

neutral  Tony M: I think mere 'over-current' is too reductive here. As we are talking about VERY HIGH surge currents (10 kA), I think this really is talking about transient surges of the lightning strike variety.

courant d'appel (courant de surcharge)


Explanation:
Same current type like that asked before, but with different focus, cf. https://eng.proz.com/kudoz/english-to-french/electronics-ele...

Inrush current, input surge current, or switch-on surge is the maximal instantaneous input current drawn by an electrical device when first turned on.

disagree  Jennifer Levey: If the same ST also refers to 'switch-on surge', then a different term is needed here. And you are confusing 'surge' with 'overload' - again, they're different concepts, with different translations.
58 mins
  -> Courant de surcharge is also proposed. Please read: 'Same current type like that asked before, but with different focus'. Both terms describe the same effect.
disagree  Herbie: Another CL5-Superflop. "Courant d'appel" = pick-up current of a contactor, widely known among electricians

  -> If I, as an electrical engineer, know both terms and their different aspects, I may well use CL 5. And the references support this.

courant de crête


Explanation:
Le courant crête est l'intensité du courant qu'un circuit absorbe pendant un temps plus ou moins court (et il est supérieur au courant de travail). Cet effet se produit dans certains circuits, lorsqu'une tension leur est appliquée.

neutral  Jennifer Levey: The question is about 'surge', not 'peak'.

disagree  Tony M: That would translate 'peak' current, which is a quite different concept from 'surge' current.
