Practical Notes
- Interrupting capability is 35 A at rated voltage — confirm the circuit's prospective fault current stays below this.
- Fast element suits resistive and semiconductor loads rather than motors with high inrush.
- Because it opens within milliseconds, downstream semiconductors see less let-through energy.
- Working voltage must stay at or below 32 Vac/dc; a lower-rated part is not a safe substitute.
- Do not upsize beyond 2.5 A to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
- automotive

Questions and Answers
What are the ratings of the 0603FA2.5-R?
2.5 A continuous at 32 Vac/dc, interrupting rating 35 A at rated voltage.
Is the 0603FA2.5-R fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the 0603FA2.5-R be used on a higher fault-current circuit?
No — its interrupting rating is 35 A at rated voltage. Choose a part whose breaking capacity exceeds the prospective fault current.
