TUNED TO THIS CLIP

This is why an electrical wire suddenly starts getting hot.

3-Phase Supply → MCCB → VFD → Motor → Mechanical Output.

When two phases touch, a phase-to-phase short circuit occurs. A very high fault current flows between the phases, causing a sudden voltage disturbance. Protective devices such as MCBs, MCCBs, or relays should trip quickly to isolate the fault. Two phases touch → high fault

If one phase is lost while the motor is running, it enters single-phasing. The motor may keep running but draws excessive current in the remaining phases, causing overheating and possible winding damage. Phase loss → high current → overheating → motor failure

What is really happening.

Here you can see the internal components of a fuse.

That relay animation is surprisingly satisfying!
Love how clearly it explains the process!
