That means you pair it with upstream protection (a fuse or circuit breaker) and use it as a service disconnect or maintenance switch. Rated continuous current Iu is 160 A. The switch carries 4 auxiliary switches HQ (changeover contacts). Mechanical endurance is 15,000 operating cycles. Power loss is 38 W maximum at rated current. That is the heat the switch dissipates into the enclosure. ## Where it is used and how it mounts This switch disconnector is designed for panel mounting. The main circuit connection is busbar connection via front terminals — meaning it bolts directly to a busbar system, not to individual wires. That makes it a natural fit for a main distribution board or a sub-distribution panel where you need a group of disconnects fed from a common bus. The front protection class is IP40 — suitable for dry indoor panels where tools or fingers cannot accidentally contact live parts. ## What it is not — and why that matters This is not a circuit breaker. It has no overcurrent release, no short-circuit protection, no undervoltage release, no trip indicator, and no communication function. It is a pure switch disconnector. If your application requires overcurrent protection, look at the 3VA1 molded case circuit breaker variants (like 3VA1110-5EE32-0DC0) which include a TM220 release and line protection. That peer is a 3-pole 100 A MCCB with the same 70 mm depth and 130 mm height but narrower width (76.2 mm). It will not drop into a panel wired for this 4-pole disconnect without rewiring — different pole count, different connection method (lug terminal vs busbar).","metaTitle":"Siemens 3VA1116-1AA42-0AE0 Switch Disconnector, 160 A, 4-Pol","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0AE0 switch disconnector, 160 A rated continuous current, 4-pole, 690 V AC / 600 V DC.
