    Design Notes

    • Interrupting capability is 10000A@125VAC — confirm the circuit's prospective fault current stays below this.
    • 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 1.5 A to stop nuisance trips — fix the cause instead.

    Where It Is Used

    Typical places this fuse turns up:

    • UPS
    • adapter
    • industrial control
    • lighting
    • appliance
    • surge
