Selection Notes

Interrupting capability is 63 A at rated voltage, 50 Hz — confirm the circuit's prospective fault current stays below this.
Time-delay element rides through motor starting and capacitive inrush without nuisance opening.
Startup surges of several times rated current are tolerated for a short window.
Do not upsize beyond 6.3 A to stop nuisance trips — fix the cause instead.

Typical Applications

Engineers usually specify it for these duties:

EV
adapter
