Precautions
Before Using High Alternating Current Sensors, Snap-on Type
• Do NOT drop or apply any other mechanical stress.
• Preliminary study is required when heating by current conduction.
• Do NOT use the High Alternating Current Sensors, Snap-on Type, opened between secondary output terminals. Heat build-
up in the magnetic core may occur, resulting in damages to the parts by melting of the coil.
