The interrupting capacity is what drives coordination: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 9 kA at 690 V. ## Auxiliary and release configuration — what ships inside the cover ## Physical fit — dimensions for panel layout That 138 mm width is the standard 3-pole MCCB footprint for the SENTRON 3VA2 frame at this rating — it occupies the same panel cutout as other 3VA2 3-pole units, so a panel laid out for a 3VA2116-5HL32-0AK0 will accept this 400 A frame without re-drilling the mounting plate. The 110 mm depth includes the arc-chamber housing; allow clearance for the shunt-trip wiring and auxiliary cable exit at the top.","metaTitle":"Siemens 3VA2440-5HN32-0KH0 SENTRON MCCB, 400A, 3-Pole, 187kA","metaDescription":"Siemens SENTRON 3VA2440-5HN32-0KH0 molded case circuit breaker, 400A continuous, 3-pole, 187kA IC at 240VAC.
