The 138 mm width, 248 mm height, and 110 mm depth fit the standard SENTRON 3VA footprint, so a panel laid out for a 3VA frame accepts this unit without re-drilling the mounting plate. ## Temperature derating — don't lose capacity at the bus At 55 °C it derates to 384 A, at 60 °C to 376 A, at 65 °C to 368 A, and at 70 °C to 360 A.","metaTitle":"Siemens 3VA2440-5HN32-0AE0 SENTRON MCCB, 400 A, ETU350","metaDescription":"Siemens SENTRON 3VA2440-5HN32-0AE0 molded case circuit breaker, 400 A rated continuous current, ETU350 electronic trip unit, 3-pole line protection.
