Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V — that 187 kA at 240 V covers high-fault utility feeds; the 690 V figure is low enough that you verify coordination with the upstream device on a 690 V system.
Footprint is 184 mm wide by 248 mm tall by 110 mm deep. That 184 mm width is the critical dimension for a 4-pole MCCB — it spans four pole cavities plus the mechanism housing. Mounting is bolt-on or plug-in via the SENTRON base; no DIN-rail clip on this frame size. Verify the cutout pattern against the panel's backplate before drilling — the 3VA family uses a specific bolt-hole template that differs from older 3VL or 3VF footprints.
Auxiliary switch and variant note
This order code ships with three factory-fitted auxiliary switches (HQ design). The base switch variant is 3VA2340-5HL42-0AA0 — the -0AD0 suffix adds the three aux switches. If your application needs shunt trip or ground-fault alarm, you order a different suffix or add a field-installable accessory module.
