What’s the Breaking Time Between trip order &arc Extension in NS1600b - 3 Poles - Fixed - Micro logic 2.0?
This information is not provided for NS breakers as they are limitor breakers. Generally break time is less then ACB breakers due to the limitation..
Closing time depends on the way the breaker is operated, closing time is less than 80ms.
In our Compact NS range, the maximum breaking time of the contacts is < 60 ms. And the break time between tripping order and arc extinction is less than 10 ms. It is the total time to clear the fault which includes time taken by the poles to get the open position but mainly the time to clear the arc through the arc chute chamber
