What this MCCB brings to a panel
The 63 A rating holds flat from 40 °C to 50 °C — no derating needed in a typical warm enclosure — then steps down to 60.48 A at 55 °C and 56.7 A at 70 °C, so a panel builder can plan the fill factor without guessing thermal margin. Breaking capacity hits 52.5 kA at 240 V, drops to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. That 52.5 kA at 240 V covers high-fault utility feeds in North American 240/120 V split-phase or 240 V delta services; the 32 kA at 415 V is the number to check for European 400 V grids. The overcurrent release is a TM210 thermal-magnetic unit — fixed thermal curve, fixed magnetic trip. No electronic adjustment, no communication module, no phase-failure detection. It's a workhorse breaker for straightforward feeder or branch protection where you don't need metering or remote trip.
Footprint and integration
No auxiliary contacts on this variant (order code suffix indicates 'without'), so if you need a status feedback contact, you'll add the separate auxiliary trip module 3VA9608-0BB25.
