protective extra-low voltage circuit
earthed circuit operating at safety extra-low voltage which is separated from other circuits
by basic insulation and protective screening, double insulation or reinforced insulation
NOTE 1 Protective screening is the separation of circuits from live parts by means of an earthed screen.
NOTE 2 A protective extra-low voltage circuit is also known as a PELV circuit.
