Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. At 415 V that is well above typical utility fault levels in most industrial installations, so you can use this MCCB as the main incoming device without worrying about cascading failure upstream. ## Physical fit — dimensions and panel integration The 3VA2063-7HN42-0AA0 measures 181 mm high, 140 mm wide, and 86 mm deep (7.1 × 5.5 × 3.4 inches). No communication module built in (Communication Function: No, Other Measurement Function: No), so this is a straight electromechanical breaker with the ETU350 handling the protection curve. If you need remote trip indication or power monitoring, you step up to the 3VA2 series with the COM module. Latching endurance is 20,000 operations. The ETU350 is field-adjustable for long-time and short-time pickup.","metaTitle":"Siemens 3VA2063-7HN42-0AA0 SENTRON MCCB, 63A 4-Pole, 330kA a","metaDescription":"Siemens 3VA2063-7HN42-0AA0 SENTRON molded case circuit breaker, 63A rated continuous current, 4-pole, ETU350 trip unit, 330kA breaking capacity at 240V AC.
