Selection Notes
- Interrupting capability is 35–63 A @ 250 VAC (rating-dependent); 35 A @ 125 VDC — 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 250 VAC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 6.3 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- EV
- industrial control

Q&A
What are the ratings of the 37016300000?
6.3 A continuous at 250 VAC, interrupting rating 35–63 A @ 250 VAC (rating-dependent); 35 A @ 125 VDC.
Is the 37016300000 fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the 37016300000 be used on a higher fault-current circuit?
No — its interrupting rating is 35–63 A @ 250 VAC (rating-dependent); 35 A @ 125 VDC. Choose a part whose breaking capacity exceeds the prospective fault current.
