Selection Notes
- Interrupting capability is 200 A–10 kA @ 250 VAC; 300 A–10 kA @ 450 VDC — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 250 VAC / 450 VDC; 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:
- EV
- telecom
