Selection Notes
- Interrupting capability is 50 A @ 72 VAC; 50 A @ 60 VDC; 100 A @ 75 VDC — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 72 VAC / 75 VDC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 7 A to stop nuisance trips — fix the cause instead.
Typical Applications
Engineers usually specify it for these duties:
- battery
- EV
- charging
- telecom
- surge
