Its 4-pole design (3 phases + neutral) handles 63 A continuously across the full ambient range from 40 °C to 70 °C without derating, which means it holds its rating in a hot enclosure or near a curing press without needing a larger frame. ## Shunt trip and switching duty It has no undervoltage release, no auxiliary contacts, and no communication module. The mechanical service life is 15 000 switching cycles typical, which suits infrequent isolation rather than daily motor starting. For higher-cycle applications, a contactor would be the better choice. The 70 mm depth and 101.6 mm width fit standard SENTRON 3VA1 panel footprints. Maximum power loss is 38 W at rated current.","metaTitle":"Siemens 3VA1163-1AA42-0KA0 SENTRON MCCB, 63 A, 4-Pole, Shunt","metaDescription":"Siemens 3VA1163-1AA42-0KA0 SENTRON 4-pole MCCB switch disconnector, 63 A continuous at 70 °C, 690 V AC / 600 V DC, shunt trip release, IP40 front, current production.
