I am not sure if you're agreeing with me or not. Assuming you are, thank you. Nanoseconds could save you but milliseconds will likely not. It takes very little

I am not sure if you're agreeing with me or not. Assuming you are, thank you. Nanoseconds could save you but milliseconds will likely not. It takes very little to explode a chip that isn't fortified and designed for robustness.

Instantaneous trip will kick in with 3-5x over current which happens in nanoseconds. Thermal overloads take longer so they don’t nuisance trip on inrush motor current (not applicable to single-phase motors due to start/run capacitors) Also, what chip is taking in line voltage single-phase AC at 120V or 208V or 277V or 480V? All of the semiconductors I am familiar with run on low voltage DC with an inverter between AC and DC.
