The ETU330 electronic trip unit handles the overcurrent protection curve, and the breaker is rated for line protection duty (cable and busbar feeder protection, not motor starting). Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. ## Panel fit and physical integration Dimensions are 248 mm high, 138 mm wide, 110 mm deep — a standard 3-pole MCCB footprint for the SENTRON 3VA platform. If you need auxiliary contacts or remote indication, those are add-on accessories that clip onto the side or front.","metaTitle":"Siemens 3VA2440-5HM32-0AA0 SENTRON MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens 3VA2440-5HM32-0AA0 SENTRON molded case circuit breaker, 400 A rated, 3-pole, 187 kA breaking capacity at 240 V AC.
