    Design Notes

    • Interrupting capability is 200 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.
    • 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 7 A to stop nuisance trips — fix the cause instead.

    Common Questions

    What are the ratings of the MDL-7-R?

    7 A continuous at 250 Vac, interrupting rating 200 A at 250 Vac; 10,000 A at 125 Vac.

    Is the MDL-7-R fast-acting or time-delay?

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

    Can the MDL-7-R be used on a higher fault-current circuit?

    No — its interrupting rating is 200 A at 250 Vac; 10,000 A at 125 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
