Practical Notes
- Interrupting capability is 50 A @ 125 VAC/VDC — confirm the circuit's prospective fault current stays below this.
- Working voltage must stay at or below 125 VAC/VDC; a lower-rated part is not a safe substitute.
- Do not upsize beyond 1 A to stop nuisance trips — fix the cause instead.
Application Scenarios
Common installation contexts include:
- EV
