It is a 4-pole device designed for isolation and switching duty — it does not provide overload or short-circuit protection, so it pairs with upstream protection devices in a distribution panel. ## Current rating and thermal behaviour The 3VA1116-1AA42-0DC0 holds its full 160 A rating from 40 °C through 50 °C ambient, then derates linearly to 150 A at 70 °C. ## Voltage ratings and auxiliary hardware Rated insulation voltage is 800 V, with AC operating voltage at 690 V and DC at 600 V — suitable for 400 V and 690 V three-phase systems common in European industrial distribution. The front terminal accepts busbar connection for the main circuit. Two HQ auxiliary switches (CO contacts) are factory-fitted, and the design accepts an optional motor drive for remote switching. The IP40 front protection is standard for panel-mounted switchgear; the enclosure provides the rest of the IP rating. The closest peer in the SENTRON family is the 3VA2116-5HM42-0CC0, which is a full molded-case circuit breaker (MCCB) with electronic overcurrent release (ETU330) and ground-fault monitoring. The 3VA1116 is a switch disconnector only — no trip unit, no protection. Physically, the 3VA1116 is significantly smaller: 70 mm deep × 101.6 mm wide × 130 mm high versus 86 mm × 140 mm × 181 mm for the 3VA2116. It will not drop into a cutout designed for the 3VA2116 without panel rework. The mechanical life of the 3VA1116 is 15,000 cycles versus 25,000 for the 3VA2116, reflecting its lighter-duty isolation role.","metaTitle":"Siemens 3VA1116-1AA42-0DC0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens 3VA1116-1AA42-0DC0 SENTRON switch disconnector, 160 A rated current at 40-50 °C, 4-pole, with undervoltage release and 2 HQ auxiliary switches.
