The 630 A rating is the continuous current at 40 °C ambient; the thermal derating table shows it carries 612 A at 45 °C, 593 A at 50 °C, and drops to 520 A at 70 °C — so if the panel ambient runs hot, the effective ampacity is lower than the nameplate figure. Breaking capacity is the other headline number: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 9 kA at 690 V. ## Panel integration — dimensions and mounting The 3VA2463-7HN42-0AA0 measures 248 mm high by 184 mm wide by 110 mm deep. That 184 mm width for a 4-pole frame is standard for the 3VA2 platform — it occupies the same footprint as other 4-pole units in the series. The lifecycle stage is listed as current — meaning the manufacturer continues to produce this order code without a phase-out notice. No successor has been assigned.","metaTitle":"Siemens 3VA2463-7HN42-0AA0 SENTRON MCCB, 630A, 4-Pole, ETU35","metaDescription":"Siemens 3VA2463-7HN42-0AA0 SENTRON molded case circuit breaker, 630A continuous, 4-pole, ETU350 release.

The 3VA2110-7HK42-0AA0 and 3VA2116-5JP32-0AE0 are also in the 3VA2 family but differ in poles, trip units, and ratings.

The 3VA2463-7HN42-0AA0 is physically larger (248 x 184 x 110 mm vs the smaller frame dimensions) and requires busbars or cable rated for 630 A.
