    Practical Notes

    • Interrupting capability is 1,500 A at 250 Vac — confirm the circuit's prospective fault current stays below this.
    • 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 630 mA to stop nuisance trips — fix the cause instead.
