Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 17 kA at 690 V — figures that govern its fault-clearing capability at the point of installation. Above that, derate to 384 A at 55 °C, 376 A at 60 °C, 368 A at 65 °C, and 360 A at 70 °C. Maximum power loss is 66 W. If the panel ambient exceeds 50 °C, the continuous current must be reduced per these values — the breaker does not self-derate. Dimensions: 248 mm height, 138 mm width, 110 mm depth. The 138 mm width across three poles is standard for this frame size — verify the backplate cutout and door cutout against the existing panel layout. The breaker accepts lug or busbar connections; the auxiliary contact block (2 aux + 1 alarm) is factory-integrated. No communication module or phase-failure detection is fitted on this variant.","metaTitle":"Siemens 3VA2440-5HL32-0BH0 SENTRON MCCB, 400A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2440-5HL32-0BH0 molded case circuit breaker, 3-pole, 400A rated continuous current, 187kA breaking at 240V AC.
