The interrupting ratings tell the real story: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 5.25 kA at 690 V.
Full 63 A rating holds through 50 °C ambient. At 55 °C it derates to 60.6 A, at 60 °C to 58.3 A, at 65 °C to 55.9 A, and at 70 °C to 53.6 A. The 86 mm depth, 105 mm width, and 181 mm height fit standard SENTRON 3VA panel cutouts; no rework needed if you're swapping a 3VA frame.
Auxiliary and trip configuration
The integrated auxiliary trip module is order code 3VA9688-0BL30, and the supplied basic switch is 3VA2163-7HN32-0AA0 — useful to know if you're stocking spares for the contact block. No undervoltage release, no phase failure detection, no communication function. This is a straightforward line-protection breaker with a voltage trigger for remote trip — not a power monitoring node.
