Intrinsic Safety i2G4 or i3aG4
(OP)
I have seen 'i2G4 or i3aG4' on certificate. It looks like to be explosion protection in accordance with JIS.
Anybody tells me what means by each figure or charactor. I have only seen code marked by IEC or CSA.

So i2G4 would be: Intrinsically Safe, between 0.4 and 0.6mm flame propigation, and up to 200 degree C temperature rating.
