Practical Notes
- Interrupting capability is 50 A at rated Vac — 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 125 Vac / 125 Vdc; 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
- lighting
- LED driver
- transformer
Buying Notes
Order code 2410FA2-5-R from Eaton, supplied in 2410 (6125 metric) surface mount. Confirm the exact suffix before release.
Questions and Answers
What are the ratings of the 2410FA2-5-R?
2.5 A continuous at 125 Vac / 125 Vdc, interrupting rating 50 A at rated Vac.
Is the 2410FA2-5-R fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the 2410FA2-5-R be used on a higher fault-current circuit?
No — its interrupting rating is 50 A at rated Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
