Selection Notes
- Interrupting capability is 50 A @ 250 VAC — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 250 VAC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 2.5 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- battery
- EV
- industrial control
- charger
