The 63 A rating is non-derated across the full operating ambient range (–), meaning this disconnector carries its full nameplate current even at 70 °C — a useful margin for panels with dense heat buildup. The front-terminal busbar connection means it lands on a standard busbar system, not cable lugs — plan the busbar drop accordingly. The 3VA1163-1AA42-0HH0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall (–). The 101.6 mm width is a standard 4-pole modular footprint for IEC switch disconnectors in this frame size. The optional motor drive allows remote switching if the panel layout requires it. ## Auxiliary and trip wiring The shunt trip (STL) release operates on 12-30 V DC or 24 V AC 50/60 Hz — a wide DC range that covers common 24 V control supplies with tolerance for voltage drop on long runs. There is no undervoltage release, so the disconnector holds closed on loss of control power; if undervoltage protection is needed, it must be added externally.","metaTitle":"Siemens 3VA1163-1AA42-0HH0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA42-0HH0 SENTRON switch disconnector, 63 A rated current, 4-pole, with shunt trip STL and auxiliary switches HQ.
