Practical 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.
- 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 600 mA to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
Questions and Answers
What are the ratings of the GMA-600-R?
600 mA continuous at 250 Vac, interrupting rating 35 A at 250 Vac; 10,000 A at 125 Vac.
Can the GMA-600-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.
