    Practical Notes

    • Interrupting capability is 4000 A @ 250 Vac/dc — 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 250 Vac / 250 Vdc; a lower-rated part is not a safe substitute.
    • Do not upsize beyond 125 mA to stop nuisance trips — fix the cause instead.

    Application Scenarios

    Common installation contexts include:

    • transformer

    Buying Notes

    Order code C308F125mA from Eaton, supplied in 3 x 8.4 mm ceramic tube, silver-plated brass end caps, optional axial leads. Confirm the exact suffix before release.

    Questions and Answers

    What are the ratings of the C308F125mA?

    125 mA continuous at 250 Vac / 250 Vdc, interrupting rating 4000 A @ 250 Vac/dc.

    Can the C308F125mA be used on a higher fault-current circuit?

    No — its interrupting rating is 4000 A @ 250 Vac/dc. Choose a part whose breaking capacity exceeds the prospective fault current.
