Hello Vithani, Yes it will trip when drawing 80% instantaneously without any delay. (Overcurrent)
What you describe above is overload protection with inverse time characteristic. It depends upon type of curve.

No It will NOT TRY Checking if you have any drive. I tried so many times in past, that drive will not TRIP instantly and I am sure for this
Well, then as per that Link, short circuit will be OVER CURRENT and what I said (80%) will be over load so it will follow the curve One more thing is, short circuit is also following same curve thats why it will trip instantaneously because short circuit current will be very high and according I2t, it should trip very fast How can drive identify difference between overcurrent and overload? because it has same parameter to monitor so I guess there should be only one curve which drive follows What you said is true but I guess its more likely ralated to switchgear not for drives I am interested to know about that curve? from where we can find that? May be any siemens Engg would have Idea I hope I am clear Deep Regards, Devesh |
