    Practical Notes

    • Interrupting capability is 35 A — 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.
    • Glass body lets you inspect the element after a fault.
    • Best kept for lower fault-current circuits where visual diagnosis matters.
    • Working voltage must stay at or below 250 Vac; a lower-rated part is not a safe substitute.
    • Do not upsize beyond 0.75 A to stop nuisance trips — fix the cause instead.

    Application Scenarios

    Common installation contexts include:

    • EV
    • adapter
    • appliance

    Buying Notes

    Order code C518-750-R from Eaton, supplied in 5 x 15 mm glass tube, nickel-plated brass end caps, axial leads, optional fluoropolymer sleeve. Confirm the exact suffix before release.

    Questions and Answers

    What are the ratings of the C518-750-R?

    0.75 A continuous at 250 Vac, interrupting rating 35 A.

    Is the C518-750-R fast-acting or time-delay?

    It is fast-acting. Expect it to open quickly on overload.

    Can the C518-750-R be used on a higher fault-current circuit?

    No — its interrupting rating is 35 A. Choose a part whose breaking capacity exceeds the prospective fault current.
