Selection Notes
- Interrupting capability is 50 A @ 125 VAC/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.
- Working voltage must stay at or below 125 VAC/VDC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 5 A to stop nuisance trips — fix the cause instead.

Q&A
What are the ratings of the 0460005.ER?
5 A continuous at 125 VAC/VDC, interrupting rating 50 A @ 125 VAC/VDC.
Is the 0460005.ER fast-acting or time-delay?
It is time-delay. It tolerates short inrush surges.
Can the 0460005.ER be used on a higher fault-current circuit?
No — its interrupting rating is 50 A @ 125 VAC/VDC. Choose a part whose breaking capacity exceeds the prospective fault current.
