It delivers a breaking capacity of 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V — figures that tell you it handles high-fault utility feeds and large transformer secondaries without cascading upstream. The shunt trip (STL) auxiliary release is integrated as standard — part number 3VA9688-0BL32 — so this breaker can be tripped remotely by a control signal, which is typical for emergency-stop circuits or supervisory shutdown in a panel. Rated insulation voltage is 800 V, and the maximum power loss at rated current is 63.5 W — a figure worth noting for enclosure thermal management when the breaker is enclosed in a non-ventilated panel. The 400 A rating holds flat from 40 °C through 50 °C ambient. Above that, it derates: 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. Operating ambient range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. If your panel ambient runs hot — say, next to a furnace line or in a poorly ventilated enclosure — the 55 °C derate to 384 A is the number to size against, not the nameplate 400 A. Dimensions are 248 mm high, 138 mm wide, 110 mm deep. The 138 mm width is the standard 3-pole MCCB footprint for this current class — it occupies three 45 mm-wide pole spaces on a DIN rail or bolted to a mounting plate. No auxiliary contacts are fitted from the factory, so if you need status feedback, plan for a separate auxiliary switch block.","metaTitle":"Siemens 3VA2440-7HL32-0JA0 SENTRON MCCB, 400A, 330kA at 240V","metaDescription":"Siemens SENTRON 3VA2440-7HL32-0JA0 molded case circuit breaker, 400A rated, 3-pole, line protection, ETU320 release, 330kA at 240V.
