标题: IEC 61058-1 Annex F中这一句如何理解?
F.1.2.1 Switches having both resistive and motor load ratings are not suitable for switching a
combined load of the full resistive load plus the full motor load. Such switches can be used for
switching a combined resistive load plus a motor load, providing the vector sum of the resistive
current and six times the steady-state motor current does not exceed either the resistive current
rating or six times the motor current rating, whichever is greater, and depending upon the
power factor of the combined load. The vector sum of the resistive current and the steady-state
current of the motor shall not exceed the resistive current rating.
