Practical Notes
- Interrupting capability is 35 A AC; 35 A DC — 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.
- Footprint 2 x 1.6 mm — check clip or holder compatibility before substitution.
- Working voltage must stay at or below 32 Vdc; a lower-rated part is not a safe substitute.
- Do not upsize beyond 12 A to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
- surge
Buying Notes
Order code 3216TD12-R from Eaton, supplied in 3.2 x 1.6 mm (1206 imperial / 3216 metric). Confirm the exact suffix before release.
Questions and Answers
What are the ratings of the 3216TD12-R?
12 A continuous at 32 Vdc, interrupting rating 35 A AC; 35 A DC.
Is the 3216TD12-R fast-acting or time-delay?
It is slow-blow. It tolerates short inrush surges.
What size is the 3216TD12-R?
It measures 2 x 1.6 mm. Match the holder or clip to this footprint.
