I want to sense the inrush current and as well as over current ,i want to protect my circuit from more than rated current.if i use a current sensor and protect my circuit,circuit will be tripped during inrush also,which is not my requirement.I should not use NTC also because i want to moniter inrush also.
supply voltage is DC.
Please help me about inrush handling.

Thanks
ravi
 

Dear Ravi
Hi
The most usual way is , using a series resistance with your power line and then a triac to bypass it after that impulse . or another way , is using an RLCD network .

Inrush is best dealt with by soft start, keeping the current
below the overcurrent trip threshold. Then you have only
one current sense problem.
