It provides visible isolation for a circuit — it makes and breaks load current but carries no overload or short-circuit protection. The part is designed for applications where disconnection is needed downstream of a separate protective device, such as a main breaker or fuse. Rated continuous current Iu is 63 A — sized for a 63 A busbar tap or feeder. Max AC operational voltage is 690 V 50/60 Hz; max DC is 600 V. The 4-pole configuration allows switching of three phases plus neutral in TN or TT systems, or four-phase DC circuits. Front terminal busbar connection matches the SENTRON busbar system. IP40 on the front. ## Auxiliary contacts and options Comes with 3 auxiliary switches HQ (high-quantity, meaning multiple changeover contacts) — 3 CO contacts total. Motor drive is available as an optional add-on (product extension optional motor drive = Yes). Maximum power loss is 38 W.","metaTitle":"Siemens 3VA1163-1AA42-0AD0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA42-0AD0 SENTRON switch disconnector, 63 A rated continuous current, 4-pole, 690 V AC / 600 V DC.
