Practical Notes
- Interrupting capability is 40 A @ 250 VAC (IEC); 50 A @ 250 VAC (UL) — 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 4 A to stop nuisance trips — fix the cause instead.
Buying Notes
