Rated insulation voltage Ui is 800 V, giving headroom on 690 V systems where the interrupting rating drops to 9 kA — that 9 kA at 690 V is the hard limit; coordination studies should stay inside it. ## Thermal derating and ambient reality The 630 A base rating holds at 40 °C. At 50 °C it derates to 593 A; at 60 °C to 557 A; at 70 °C to 520 A. Maximum power loss is 162 W. That heat has to leave the enclosure — factor it into the panel cooling budget, especially in a sealed IP54 cabinet. ## ETU330 trip unit and N-conductor protection The ETU330 is an electronic overcurrent release with adjustable N-conductor protection — settable to OFF, 50 %, or 100 % of the phase rating. That matters when the neutral carries harmonic content from VFDs on the same bus. If the spec calls for remote tripping or load-shedding, the 3VA2 platform accepts plug-in accessories, but this order code ships bare. Dimensions: 248 mm high, 184 mm wide, 110 mm deep. No rewiring needed if replacing a 5SQ2670-2YA06 or similar 4-pole MCCB on the same bus; the lug centers and phase spacing match the 3VA2 platform. Front protection is IP40 — tools and fingers are kept out, but the enclosure itself must provide the overall IP rating for washdown or dust environments. ## Ambient and storage limits","metaTitle":"Siemens 3VA2463-7HM42-0AA0 SENTRON MCCB, 630 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2463-7HM42-0AA0 SENTRON molded case circuit breaker, 630 A at 40 °C, 4-pole, ETU330 electronic trip unit, 330 kA at 240 V.
