It carries a breaking capacity of 440 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 73.5 kA at 690 V — numbers that tell you this breaker is sized for high-fault main feeders, not branch circuits. The ETU330 gives you adjustable overload and short-time delay curves, so you can coordinate selectively downstream without sacrificing speed on a hard fault. Ground-fault monitoring uses summation current formation on L + N conductors, and the N-conductor protection is adjustable to OFF, 50%, or 100% of the phase rating — useful when you're feeding a panel with a reduced neutral or a harmonic load that needs a different pickup. At 60 °C it derates to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A. Dimensions are 120 mm deep, 280 mm wide, 320 mm tall; it's a substantial footprint that needs a 4-pole cutout in the mounting plate. The 330 W maximum power loss means you'll want some airflow through the compartment, not a sealed dead-front.","metaTitle":"Siemens 3VA2510-7HM42-0AA0 SENTRON MCCB, 1000 A, 4-Pole, ETU","metaDescription":"Siemens 3VA2510-7HM42-0AA0 SENTRON molded case circuit breaker, 1000 A rated, 4-pole, ETU330 trip unit, 440 kA at 240 V.
