Design Notes
- Interrupting capability is 1500A@250VAC — confirm the circuit's prospective fault current stays below this.
- 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 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.
Where It Is Used
Typical places this fuse turns up:
- UPS
- EV
- adapter
- industrial control
- lighting
- appliance
