Selection Notes
- Interrupting capability is 50 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 63 Vdc; a lower-rated part is not a safe substitute.
- Do not upsize beyond 0.5 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- battery
- EV
- transformer

Q&A
What are the ratings of the 0603HV500-R?
0.5 A continuous at 63 Vdc, interrupting rating 50 A at rated voltage.
Is the 0603HV500-R fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the 0603HV500-R be used on a higher fault-current circuit?
No — its interrupting rating is 50 A at rated voltage. Choose a part whose breaking capacity exceeds the prospective fault current.
