Selection Notes
- Interrupting capability is 35 A at 250 Vac; 10,000 A at 125 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.
- Footprint 5 x 20 mm — check clip or holder compatibility before substitution.
- Working voltage must stay at or below 250 Vac; a lower-rated part is not a safe substitute.
- Do not upsize beyond 200 mA to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- EV
Q&A
What are the ratings of the GMA-200-R?
200 mA continuous at 250 Vac, interrupting rating 35 A at 250 Vac; 10,000 A at 125 Vac.
Is the GMA-200-R fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
What size is the GMA-200-R?
It measures 5 x 20 mm. Match the holder or clip to this footprint.
Can the GMA-200-R be used on a higher fault-current circuit?
No — its interrupting rating is 35 A at 250 Vac; 10,000 A at 125 Vac. Choose a part whose breaking capacity exceeds the prospective fault current.
