Breaking capacity is 242 kA at 240 VAC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V — per the datasheet. That 242 kA at 240 V is the headline figure; at 415/440 V the 187 kA still covers most industrial fault levels. Dimensions are 248 mm height, 138 mm width, 110 mm depth. ## Key ratings and thermal performance Maximum power loss is 63.5 W. The 400 A rating is the same at every 5 °C step from 40 to 70 °C, which simplifies panel thermal calculations. ## Built-in shunt trip release No auxiliary switch is fitted; if status feedback is needed, a separate auxiliary switch module must be added.","metaTitle":"Siemens 3VA2440-6HN32-0KA0 SENTRON MCCB, 400 A, 3-Pole, 242","metaDescription":"Siemens SENTRON 3VA2440-6HN32-0KA0 molded case circuit breaker, 400 A continuous, 3-pole, 242 kA breaking capacity at 240 VAC.
