ROTECTION
The unit is tested and approved for branch circuits up to 20A. External protection is only required if the supplying
branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and
local requirements.
branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and
local requirements.
If an external fuse is necessary or utilized, a minimum value is required to avoid undesired tripping of the fuse.
