What would be the cause and countermeasures for an input breaker tripping or an external fuse blowing?


Probable Cause

The breaker may have tripped due to the inrush current from the power supply.

Possible Countermeasure

Confirm the inrush current for each product, then provide fuses and breakers to match. (The power supply inrush current can be from several times to several tens of times higher than the current during normal operation.)
