Selection Notes
- Interrupting capability is 50 A @ 32 V AC/DC — 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.
- Ceramic body holds higher breaking capacity than glass at the same footprint.
- It is the usual choice where prospective fault current is high.
- Working voltage must stay at or below 32 V; a lower-rated part is not a safe substitute.
- Do not upsize beyond 0.375 A to stop nuisance trips — fix the cause instead.

Part Number and Packing
Order code 0467.375NR from Littelfuse, supplied in 0603 (approx. 1.6 × 0.8 mm). Confirm the exact suffix before release.
Q&A
What are the ratings of the 0467.375NR?
0.375 A continuous at 32 V, interrupting rating 50 A @ 32 V AC/DC.
Is the 0467.375NR fast-acting or time-delay?
It is fast-acting. Expect it to open quickly on overload.
Can the 0467.375NR be used on a higher fault-current circuit?
No — its interrupting rating is 50 A @ 32 V AC/DC. Choose a part whose breaking capacity exceeds the prospective fault current.
