Interrupting capacity hits 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, then 187 kA at 500 V, and 9 kA at 690 V. ## Panel fit and auxiliary configuration The depth of 110 mm is the dimension to watch when clearing the gland plate or backpanel; the width of 138 mm sets the DIN-rail or mounting-plate pitch. The trip indicator is present, so a quick visual scan confirms the breaker state without opening the door.","metaTitle":"Siemens 3VA2440-7HL32-0CL0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens 3VA2440-7HL32-0CL0 SENTRON molded case circuit breaker, 400 A continuous, 3-pole, 330 kA at 240 V.
