The 160 A rating means it can handle the full load current of a large motor control center feeder or a sub-distribution board without derating at 40 °C ambient. Rated operational voltage reaches 690 V AC (50/60 Hz) and 600 V DC, covering standard 400/480 V three-phase systems and many DC bus applications. This unit carries 2 auxiliary switches (HQ type) for remote status indication, and the design accepts an optional motor drive for remote switching. Main circuit connection is via front busbar terminals, typical for panel-mounted disconnect switches in MCCB footprints. The limited short-time withstand rating (2 kA for 1 s, 2 kA for 0.5 s) means it can survive a fault current up to 2 kA without damage while upstream protection clears — adequate for most secondary distribution panels where the available fault current is below 2 kA. The mechanical endurance of 15,000 latching operations suits frequent switching in process or maintenance isolation roles. No official successor order code exists because the part is active. The SENTRON 3VA platform is the current generation; there is no need to cross-reference to an older series. Dimensions: 70 mm depth, 101.6 mm width, 130 mm height. Front busbar terminals accept standard busbar systems for the main circuit — plan for busbar drop connections rather than cable lugs. Maximum power loss of 38 W at rated current means the enclosure must dissipate that heat — factor it into the thermal budget for a multi-disconnect panel.","metaTitle":"Siemens 3VA1116-1AA42-0AC0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA42-0AC0 switch disconnector, 160 A rated continuous current, 4-pole, 690 V AC / 600 V DC.
