The 400 A rating holds flat from 40 °C through 50 °C ambient (-), then derates to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C (-). Breaking capacity at 690 V is 52.5 kA — enough for most 690 V industrial networks, but verify against your transformer impedance and fault study. Front-face protection is IP40, suitable for dry indoor switchgear; no washdown rating. Max power loss is 96 W; factor that into enclosure thermal rise calculations.","metaTitle":"Siemens SENTRON 3VA2340-7HL32-0AH0 MCCB, 400 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0AH0 molded case circuit breaker, 400 A rated, 3-pole, ETU320 trip unit, 330 kA breaking at 240 V.
