Practical Notes
- Interrupting capability is 100 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.
- 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 2.5 A to stop nuisance trips — fix the cause instead.

- EV
Questions and Answers
What are the ratings of the AGC-2-1/2-R?
2.5 A continuous at 250 Vac, interrupting rating 100 A at 250 Vac; 10,000 A at 125 Vac; 1,000 A at 32 Vac.
Can the AGC-2-1/2-R be used on a higher fault-current circuit?
No — its interrupting rating is 100 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.
