The 400 A rating holds flat from 40 °C through 50 °C, then derates to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C. In a sealed enclosure or high-ambient machine cabinet, that means you lose 60 A by the time the internal air hits 70 °C — plan the load accordingly or add ventilation. Dimensions are 248 mm high × 138 mm wide × 110 mm deep, which fits the standard SENTRON 3VA mounting footprint; the panel cutout and bus-bar spacing match the existing 3VA line.","metaTitle":"Siemens 3VA2340-7HL32-0BA0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2340-7HL32-0BA0 molded case circuit breaker, 400 A continuous, 3-pole, 330 kA at 240 V.
