Selection Notes
- Interrupting capability is 50 A AC; 50 A 125 Vdc — 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 250 Vac; a lower-rated part is not a safe substitute.
- Do not upsize beyond 2 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- motor drive
- EV
- adapter

Q&A
What are the ratings of the 1025TD2-R?
2 A continuous at 250 Vac, interrupting rating 50 A AC; 50 A 125 Vdc.
Is the 1025TD2-R fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the 1025TD2-R be used on a higher fault-current circuit?
No — its interrupting rating is 50 A AC; 50 A 125 Vdc. Choose a part whose breaking capacity exceeds the prospective fault current.
