@ 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...

Hi, I need to know the "maximum interrupting time" of the FW/HFW Molded-Case Circuit Breakers (see the attached time-current curves).Thanks
