At 55 °C it carries 385 A, at 60 °C it carries 370 A, and at 70 °C it carries 340 A. That thermal curve means this breaker can sit in a warm panel without losing capacity until you cross 50 °C, which is useful for enclosures with multiple heat sources. Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. Dimensions are 248 mm height, 138 mm width, and 110 mm depth. The 138 mm width is the DIN-rail or mounting-footprint span; three-pole breakers in this class typically occupy three 45 mm modular spaces, so the 138 mm width is consistent with a 3 x 45 mm = 135 mm footprint plus tolerance.","metaTitle":"Siemens 3VA2340-5HL32-0AD0 SENTRON MCCB, 400 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2340-5HL32-0AD0 molded case circuit breaker, 400 A rated, 187 kA interrupting at 240 V.
