The 3-pole construction suits three-phase circuits in switchboards, motor control centers, and main distribution panels. ## Breaking capacity and fault handling Breaking capacity is 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. A trip indicator and voltage trigger are built in, so the breaker reports its state electrically. Dimensions are 138 mm wide, 248 mm high, and 110 mm deep. Maximum power loss is 63.5 W, which should be factored into the enclosure thermal budget, especially in a multi-breaker lineup. The base switch variant is 3VA2440-6HL32-0AA0; this order code adds a shunt trip release (STL) and the HQ auxiliary switch block.","metaTitle":"Siemens 3VA2440-6HL32-0HH0 SENTRON MCCB, 400 A, 3-Pole, 110","metaDescription":"Siemens SENTRON 3VA2440-6HL32-0HH0 molded case circuit breaker, 400 A at 40 °C, 3-pole, 242 kA at 240 V.
