The 3VA1116-1AA32-0DA0: Rated continuous current Iu of 160 A defines the maximum uninterrupted current the disconnector can carry without exceeding its thermal limits — sized for a 160 A feeder or branch circuit where the upstream protection (fuse or MCCB) handles fault interruption. The rated insulation voltage Ui of 800 V and max AC operational voltage of 690 V (50/60 Hz) or 500 V DC cover standard 400/480 V three-phase panels and 500 V DC bus applications. With a width of 76.2 mm and depth of 70 mm, it fits the standard 3-pole MCCB footprint in the SENTRON 3VA1 family, matching the same DIN-rail or screw-mount hole pattern as its breaker siblings.
Deployment context: where this part belongs in a panel
This switch disconnector is intended for use as a main isolating device in a distribution board or motor control center, typically downstream of a circuit breaker or fuse that provides the short-circuit and overload protection it lacks. The front-terminal busbar connection allows direct bolting to a busbar system, saving panel space compared to wired terminals. The optional motor drive (product extension) enables remote motorized switching for automated systems.
