注 2:N 相电流最小不小于长延时整定电流电流的 1/2,最大等同于长延时整定电流
注 3:此处为 N 相电流
Note 1: 0x0000 for opening, 0x0800 for closing
Note 2: The minimum of phase-N current shall be not less than 1/2 of setting current of long-time delay, and the
maximum value shall be equal to the setting current of long-time delay.
Note 3: Here for N phase current
