Selection Notes
- Interrupting capability is 150 A @ 250 VAC — 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.
- Working voltage must stay at or below 250 VAC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 5 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- battery
- EV
- industrial control
- charger

Q&A
What are the ratings of the 80415000440?
5 A continuous at 250 VAC, interrupting rating 150 A @ 250 VAC.
Is the 80415000440 fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the 80415000440 be used on a higher fault-current circuit?
No — its interrupting rating is 150 A @ 250 VAC. Choose a part whose breaking capacity exceeds the prospective fault current.
