It carries 400 A continuously at 40 °C ambient, with the same rating holding at 45 °C and 50 °C — no derating needed until you cross 55 °C, where it drops to 384 A. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V, giving you selectivity headroom across common distribution voltages.
The 3VA2440-5HL32-0AJ0 measures 248 mm high by 138 mm wide by 110 mm deep. The auxiliary contact version (2 switches + 1 trip alarm) is already populated on the basic switch 3VA2440-5HL32-0AA0. If your BOM calls for separate alarm or status feedback, this variant saves an add-on module slot.
