    Practical Notes

    • Interrupting capability is 50 A @ 72 VAC; 50 A @ 60 VDC; 100 A @ 75 VDC — confirm the circuit's prospective fault current stays below this.
    • Time-delay element rides through motor starting and capacitive inrush without nuisance opening.
    • Startup surges of several times rated current are tolerated for a short window.
    • Working voltage must stay at or below 72 VAC / 75 VDC; a lower-rated part is not a safe substitute.
    • Do not upsize beyond 10 A to stop nuisance trips — fix the cause instead.

    Application Scenarios

    Common installation contexts include:

    • battery
    • EV
    • charging
    • telecom
    • surge

    Buying Notes

    Order code 0452010.NRL from Littelfuse, supplied in 2410 / 6125 NANO2. Confirm the exact suffix before release.

    Questions and Answers

    What are the ratings of the 0452010.NRL?

    10 A continuous at 72 VAC / 75 VDC, interrupting rating 50 A @ 72 VAC; 50 A @ 60 VDC; 100 A @ 75 VDC.

    Is the 0452010.NRL fast-acting or time-delay?

    It is time-delay. It tolerates short inrush surges.

    Can the 0452010.NRL be used on a higher fault-current circuit?

    No — its interrupting rating is 50 A @ 72 VAC; 50 A @ 60 VDC; 100 A @ 75 VDC. Choose a part whose breaking capacity exceeds the prospective fault current.
