    Practical Notes

    • Interrupting capability is 200 A at 250 Vac; 1,000 A at 125 Vac; 400 A at 125 Vdc; 1,000 A at 75 Vdc — 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.
    • Ceramic body holds higher breaking capacity than glass at the same footprint.
    • It is the usual choice where prospective fault current is high.
    • Working voltage must stay at or below 250 Vac; a lower-rated part is not a safe substitute.
    • Do not upsize beyond 25 A to stop nuisance trips — fix the cause instead.

    Questions and Answers

    What are the ratings of the ABC-25-R?

    25 A continuous at 250 Vac, interrupting rating 200 A at 250 Vac; 1,000 A at 125 Vac; 400 A at 125 Vdc; 1,000 A at 75 Vdc.

    Is the ABC-25-R fast-acting or time-delay?

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

    Can the ABC-25-R be used on a higher fault-current circuit?

    No — its interrupting rating is 200 A at 250 Vac; 1,000 A at 125 Vac; 400 A at 125 Vdc; 1,000 A at 75 Vdc. Choose a part whose breaking capacity exceeds the prospective fault current.
