It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V — figures that define its fault-interrupting capability across common distribution voltages. The 400 A rating holds flat from 40 °C to 50 °C, then derates to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. A shunt trip release (STL) is built in for remote tripping. Power loss is rated at 63.5 W maximum. In a densely packed panel, that heat must be managed — allow clearance and ventilation per Siemens mounting guidelines. ## Physical integration Dimensions: 248 mm height, 138 mm width, 110 mm depth. The 3-pole footprint is standard for this current class; panel cutout and busbar spacing should match Siemens SENTRON 3VA family mounting patterns.","metaTitle":"Siemens 3VA2440-5HL32-0JL0 SENTRON MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens 3VA2440-5HL32-0JL0 SENTRON molded case circuit breaker, 400 A rated continuous current, 3-pole, breaking capacity up to 187 kA at 240 V.
