Breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — the 690 V figure is the ceiling; if your system sits at 400 V class, the 187 kA rating gives generous SCCR headroom for most industrial service-entrance or feeder applications.
The 630 A continuous rating holds at 40 °C ambient. Above that, the breaker derates in 30 A steps per 5 °C: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. If your panel ambient runs 50 °C, plan for 570 A — not the nameplate 630 A.
The 110 mm depth fits standard MCCB panel-mount cutouts; the 138 mm width is the 3-pole frame footprint. No trip indicator or voltage trigger on this variant — the UVR coil is the only auxiliary release. The basic switch assembly is order code 3VA2463-6JP32-0AA0.
Maximum power loss is 164.5 W at rated current. That heat must be dissipated inside the enclosure; factor it into the panel cooling calculation, especially if the breaker is grouped with other high-current devices in a sealed cabinet.
