Practical Notes
- Interrupting capability is 100 A @ 350 VAC/VDC; 150 A @ 250 VAC/VDC — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 250 VAC/VDC IEC; 350 VAC/VDC UL; a lower-rated part is not a safe substitute.
- Do not upsize beyond 2 A to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
- adapter
- lighting
Buying Notes
Order code 46212000000 from Littelfuse, supplied in 10.5 × 4.5 mm NANO2 UMF. Confirm the exact suffix before release.
Questions and Answers
