The 63 A rating holds flat across the full operating temperature range from 40 °C to 70 °C, so no derating curve to chase in a warm panel. It carries a shunt trip release (STL) for 110–127 V DC or AC 50/60 Hz, meaning the disconnect can be opened remotely via a control signal — a standard requirement for emergency-stop or safety-circuit isolation on a distribution bus. Rated operating voltage is 690 V AC and 600 V DC, with an insulation voltage of 800 V. The front face is IP40-rated. Dimensions are 101.6 mm wide, 130 mm tall, and 70 mm deep. Main circuit connections are busbar-type with front terminals. An optional motor drive is available as a field-addable extension. ## Peer comparison: 3VA1110-5ED36-0AA0 The closest functional peer is the 3VA1110-5ED36-0AA0, a 3-pole molded case circuit breaker rated 100 A at 40 °C with thermal-magnetic overcurrent protection (TM210, LI characteristic). The 3VA1163-1AA42-0JA0 is a 4-pole switch disconnector with no overcurrent protection, so it cannot drop in as a breaker substitute. If the panel was specified around the 3VA1110-5ED36-0AA0, rewiring is required: the 3VA1163 is wider (101.6 mm vs 76.2 mm) and uses busbar connections rather than box terminals.","metaTitle":"Siemens 3VA1163-1AA42-0JA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0JA0 switch disconnector, 63 A rated current, 4-pole, shunt trip release.
