Selection Notes
- Interrupting capability is 35 A AC; 35 A DC — confirm the circuit's prospective fault current stays below this.
- Time-delay element rides through motor starting and capacitive inrush without nuisance opening.
- Startup surges of several times rated current are tolerated for a short window.
- 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 Vdc; a lower-rated part is not a safe substitute.
- Do not upsize beyond 6.3 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- motor drive
- EV
- adapter
- surge
Part Number and Packing
Order code 3216TD6.3-R from Eaton, supplied in 3.2 x 1.6 mm (1206 imperial / 3216 metric). Confirm the exact suffix before release.
Q&A
What are the ratings of the 3216TD6.3-R?
6.3 A continuous at 32 Vdc, interrupting rating 35 A AC; 35 A DC.
Is the 3216TD6.3-R fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the 3216TD6.3-R be used on a higher fault-current circuit?
No — its interrupting rating is 35 A AC; 35 A DC. Choose a part whose breaking capacity exceeds the prospective fault current.
