Reply Dear Max, you should verify the inrush current of the inductive load first. Kindly let me know if it is available on the Schneider site appreciate if Schneider can up load a youtube video Reply Dear Sumedha, Test procedures are explained in the mentioned standards. Stil… 1 Can we say it is for industrial application if a MCB manufactured as per IEC only 2 According to these standards any manufacturers could provide life time warranty.

The best way to avert them is tightly worded, highly enforced national regulations.
What will be be approximate short-time delay timing for A inrush? Applies to bd, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1,V a. Reply Good for making Technical wn for electrical tender. Example of Acti9 circuit breaker used for buildings and industry applications. NOTE Circuit-breakers which are dealt with in this standard may be provided with devices for automatic opening under predetermined conditions een than those of over-current and undervoltage as, for example, reversal of power or current.
In other words — in final distribution electrical switchboards of buildings which nominal current does not exceed A. Share This Page Tweet. They are both standards that specify requirements for low-voltage circuit breakers.
