Design Notes
- Interrupting capability is 200 A at 250 Vac; 10,000 A at 125 Vac; 1,000 A at 32 Vac — 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.
- 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 9 A to stop nuisance trips — fix the cause instead.

Common Questions
What are the ratings of the AGC-9-R?
9 A continuous at 250 Vac, interrupting rating 200 A at 250 Vac; 10,000 A at 125 Vac; 1,000 A at 32 Vac.
Is the AGC-9-R fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the AGC-9-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; 1,000 A at 32 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
