(Class A) low-voltage current

According to the French classification system.
The following is taken from http://www.industrie.gouv.fr/sdsi/dtss/doc/rgie/fiches/elect...

Classement des tensions

En courant alternatif :
Très basse tension TBT 50 V
Basse tension A BTA 500V
Basse tension B BTB 1000V
Haute tension A HTA 50 000V
Haute tension B HTB > 50 000V

En courant continu :
Très basse tension TBT 120 V
Basse tension A BTA 750V
Basse tension B BTB 1500V
Haute tension A HTA 75 000V
Haute tension B HTB > 75 000V

In English, though, we tend not to use the A and B subcategories, low voltage covering the 50–1000 V AC or 120–1500 V DC range.
See http://en.wikipedia.org/wiki/Low_voltage for further references.
