Design Notes
- Interrupting capability is 35 A — 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.
- Working voltage must stay at or below 125 Vac or less; a lower-rated part is not a safe substitute.
- Do not upsize beyond 250 mA to stop nuisance trips — fix the cause instead.

Common Questions
What are the ratings of the GMW-1/4?
250 mA continuous at 125 Vac or less, interrupting rating 35 A.
Is the GMW-1/4 fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the GMW-1/4 be used on a higher fault-current circuit?
No — its interrupting rating is 35 A. Choose a part whose breaking capacity exceeds the prospective fault current.
