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. ## Environmental limits","metaTitle":"SENTRON 3VA2340-5HL42-0AD0 MCCB, 4-pole, 400 A, 187 kA at 24","metaDescription":"SENTRON 3VA2340-5HL42-0AD0 molded case circuit breaker, 4-pole, 400 A rated current, 187 kA breaking capacity at 240 V AC.

It will not drop into the same panel cutout — the 184 mm width and bolt-hole pattern differ. For a 400 A 4-pole replacement, stay within the 3VA2340 frame family; the 3VA2225-5HN42-0BB0 is a 250 A 4-pole with different aux switch configuration and no direct mechanical interchange."},{"question":"What are the key ratings for 3VA2340-5HL42-0AD0?","answer":"Continuous current 400 A (derated above 50 °C).
