@ Windadct LOL you are right it is not "instantaneous"; I have attached another curve with 0.013 Amps as Inst current shown; actually you can conservatively choose 0.016 Amps around the slope region (which is the instantaneous region of operation of this breaker).
Thanks
I have MCCB data as follows:
MCCB Rating = 40 Amps (i.e. Maximum Continuous Ampere Rating at 40 degree C)
Thermal Range = 32 - 40 Amps
Magnetic Range = 200 - 400 Amps (i.e. Instantaneous Pickup Range)
Horizontal axis = Multiple of current setting (i.e. Multiples of 40 Amps - Breaking...
