    Design Notes

    • Interrupting capability is 35 A at 250 Vac; 10,000 A at 125 Vac — 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.
    • Footprint 5 x 20 mm — check clip or holder compatibility before substitution.
    • Working voltage must stay at or below 250 Vac; a lower-rated part is not a safe substitute.
    • Do not upsize beyond 750 mA to stop nuisance trips — fix the cause instead.

    Where It Is Used

    Typical places this fuse turns up:

    • EV
    • adapter
    • surge

    Common Questions

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

    750 mA continuous at 250 Vac, interrupting rating 35 A at 250 Vac; 10,000 A at 125 Vac.

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

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

    What size is the GMC-750-R?

    It measures 5 x 20 mm. Match the holder or clip to this footprint.

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

    No — its interrupting rating is 35 A at 250 Vac; 10,000 A at 125 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
