Design Notes
- Interrupting capability is Rating-dependent; up to 100 A (300/320/250 VAC per datasheet) — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 300 VAC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 1 A to stop nuisance trips — fix the cause instead.

Common Questions
What are the ratings of the 38311000000?
1 A continuous at 300 VAC, interrupting rating Rating-dependent; up to 100 A (300/320/250 VAC per datasheet).
Can the 38311000000 be used on a higher fault-current circuit?
No — its interrupting rating is Rating-dependent; up to 100 A (300/320/250 VAC per datasheet). Choose a part whose breaking capacity exceeds the prospective fault current.
