It is not a molded-case circuit breaker — it carries no overload or short-circuit protection elements. The product designation is switch disconnector, and the description confirms it ships without overload protection and without short-circuit protection. That means it functions as a manual load-break switch for isolation and disconnection, not as a protective device. The 160 A rated continuous current (Iu) sets the maximum uninterrupted load this switch can carry — sized for a 160 A feeder or downstream isolation point. The 690 V AC / 600 V DC max operational voltage covers standard 400 V three-phase panels and many DC bus applications. The 2 kA short-time withstand at 1 s and 0.5 s is the rating for fault current let-through — this switch can hold closed under a fault long enough for an upstream breaker to clear, but it does not interrupt faults itself. ## Panel integration and connections Mounts in a standard 70 mm depth footprint — the depth, width (101.6 mm), and height (130 mm) match the 3VA1 frame 160 family. Main circuit connection is busbar connection via front terminals, so it lands directly on a busbar system without lug adapters.","metaTitle":"Siemens 3VA1116-1AA42-0AB0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens 3VA1116-1AA42-0AB0 SENTRON switch disconnector, 160 A rated continuous current, 4-pole, 690 V AC / 600 V DC.
