6. 脫扣曲線與參數(shù)表 Trigger Characteristic & Parameter in the DC Range
舉例說明：( 以設(shè)置 2A 為例 )
? 當(dāng)電流大于 1.6A 時(shí)，綠燈閃爍，處于預(yù)警狀態(tài)；當(dāng)工作電流大于 2.2A 時(shí)，進(jìn)入過載狀態(tài)，該通
道黃色 LED 閃爍，如果保持過載，30 秒后關(guān)閉該通道輸出，進(jìn)入報(bào)警狀態(tài)，紅色 LED 閃爍， 此時(shí)不可
操作，10 秒后紅色恢復(fù)常亮，可以進(jìn)行復(fù)位操作；
? 當(dāng)工作電流大于 2.6A、3A、5A、7A，同上；
? 在過載期間，電流回到 2.2A 以下，LED從黃色閃爍恢復(fù)到綠色常亮，退出過載狀態(tài)；
? 短路時(shí)，脫扣時(shí)間小于 1ms。
For example: (taking 2A as an example)
? When the current is greater than 1.6A, the green light flashes and it is in warning state; when the
working current is greater than 2.2A, it enters the overload state, the yellow LED of the channel flashes,
and if the overload continues, the channel output will be turned off after 30 seconds, and it will enter the
alarm state, the red LED flashes, and it cannot be operated at this time. the red LED light will return to
normal brightness in 10 seconds, then it would keep operating to reset
? When the working current is greater than 2.6A, 3A, 5A, 7A, the same as above;
? During the overload period, when the current returns to below 2.2A, the LED light will return from
yellow flash to green brightness, it means that ECB exits the overload status;
? In case of short circuit, the tripping time is less than 1ms
