Selection Notes
- Interrupting capability is 35A@250VAC — 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 2.5 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- adapter
- industrial control
- lighting
- appliance
- surge
- transformer
Part Number and Packing
Order code 021802.5 from Littelfuse, supplied in 5 × 20 mm glass tube (IEC 60127-2 Sheet 3). Confirm the exact suffix before release.
Q&A
What are the ratings of the 021802.5?
2.5 A continuous at 250 VAC, interrupting rating 35A@250VAC.
Can the 021802.5 be used on a higher fault-current circuit?
No — its interrupting rating is 35A@250VAC. Choose a part whose breaking capacity exceeds the prospective fault current.
