Practical Notes
- Interrupting capability is 50 A AC — confirm the circuit's prospective fault current stays below this.
- Ceramic body holds higher breaking capacity than glass at the same footprint.
- It is the usual choice where prospective fault current is high.
- Working voltage must stay at or below 60 Vdc; a lower-rated part is not a safe substitute.
- Do not upsize beyond 15 A to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
- surge
Buying Notes
Order code 1025FA15-R from Eaton, supplied in 10.29 x 2.77 mm (4010 imperial / 1025 metric). Confirm the exact suffix before release.
Questions and Answers
What are the ratings of the 1025FA15-R?
15 A continuous at 60 Vdc, interrupting rating 50 A AC.
Can the 1025FA15-R be used on a higher fault-current circuit?
No — its interrupting rating is 50 A AC. Choose a part whose breaking capacity exceeds the prospective fault current.
