Please use within the rated current of each model.
¶T hree-phase three-wire EMI/EMC filter is also available as aSingle-phase input type.

EMI/EMC filters have short term peak current capability. Therefore,it can flow ~40A or ten times of rated current, non-repeated, within afew ms such as inrush current of power supply etc.
However, it should not be used under the following conditions.

Instruction Manual

Please use this while ensuring that the input current does notexceed the rated current of the EMI/EMC filter.

3 Safety Considerations¡ To apply for safety standard approval using this EMI/EMC Filter,the following conditions must be met.

¿ The unit must be used as a component of an end-use equipment.
¿ Protection earth terminal (PE) must be connected to safety
ground of end-use equipment.
