Its job is to provide visible isolation of a downstream load for lockout/tagout, maintenance access, or branch-circuit disconnection in a panel. The part carries a rated insulation voltage (Ui) of 800 V and a maximum operational voltage of 690 V AC 50/60 Hz or 600 V DC, so it suits both AC distribution and DC bus circuits up to those levels. The front terminals accept busbar connection — typical for a main-disconnect or panel-feed application where the switch ties directly to a busbar stack rather than individual cable lugs. ## Short-circuit withstand and endurance Because this is a switch disconnector without overcurrent trip elements, its fault-closing and short-time withstand ratings define the limits. The part is rated for 2 kA at both 1-second and 0.5-second intervals — meaning it must be backed by an upstream overcurrent protective device (fuse or MCCB) rated to limit let-through energy below that threshold. The mechanical endurance is 15,000 operating cycles, which is typical for a panel disconnect expected to see daily switching but not continuous high-speed operation. The 3VA1116-1AA42-0AH0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall. The 101.6 mm width corresponds to a 4-pole frame in the 3VA1 series — it occupies the same DIN-rail or mounting-plate footprint as other 4-pole 3VA1 devices, so a panel laid out for a 4-pole 3VA1 MCCB can accept this switch disconnector without re-drilling. ## Temperature range and power dissipation The motor-drive option (product extension optional) allows remote motorized operation for automated disconnection sequences.","metaTitle":"Siemens 3VA1116-1AA42-0AH0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0AH0 is a 4-pole switch disconnector, rated 160 A continuous, 690 V AC / 600 V DC.
