10. Precautions

1.  Set the breaking current two to ten times as high as the rated current.

Use the ICP-S so that the open-circuit voltage between the terminals after the ICP-S breaks 
the current will be a maximum of 50 V. Unless the ICP-S is used under these conditions, the 
mold may be damaged or internal resistance may remain after the ICP-S breaks the current.

 

2.  Do not use the ICP-S for the primary side of commercial power supply, or otherwise the mold 

may be damaged by arcing after the ICP-S breaks the current.
