The description calls it an SD100 variant: it makes and breaks load current under normal conditions and provides visible isolation, but it won't trip on overcurrent. That's the key distinction for anyone slotting this into a distribution scheme. The 160 A continuous current suits feeder or main-switch duty on sub-distribution boards. ## Undervoltage release and auxiliary contacts There's no leading-contact option on this UVR variant, so the release operates directly on the mechanism without a time delay. Two HQ auxiliary switches (form C, changeover) are fitted as standard. The HQ designation indicates high mechanical reliability — these are rated for the same 15 000 mechanical endurance cycles as the main switch mechanism. The auxiliary contacts share the same front-accessible terminal arrangement as the main circuit, which keeps wiring tidy inside the panel. ## Mounting and connections Main circuit connections are busbar-type, front-terminal arrangement — the switch is designed to bolt directly onto a busbar system or accept busbar plugs.","metaTitle":"Siemens 3VA1116-1AA32-0CC0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens 3VA1116-1AA32-0CC0 SENTRON switch disconnector, 3-pole, 160 A rated continuous current, 690 V AC / 500 V DC, with undervoltage release 120-127 V AC, 2 HQ aux switches, busb","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"70 mm","Width":"76.2 mm","Height":"130 mm","Limited To 1 S":"2 kA","Trip indicator":"No","Number of poles":"3","Product version":"in MCCB design","Voltage trigger":"No","lifecycle_stage":"current","Limited To 0.5 S":"2 kA","Product brand name":"SENTRON","Product designation":"Switch disconnector","Latching - endurance":"15 000","Undervoltage Release":"Yes","Communication Function":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"38 W","Auxiliary contact version":"2 auxiliary switches HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Rated continuous current Iu":"160 A","Rated insulation voltage Ui":"800 V","Design of the auxiliary release":"Undervoltage release (UVR)","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Max. rated operational voltage Ue with DC":"500 V","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Number of CO contacts / for auxiliary contacts":"2","Max. rated operational voltage Ue with AC 50/60Hz":"690 V","Type of electrical connection / for main current circuit":"busbar connection","Arrangement of electrical connectors / for main current circuit":"Front terminal"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=98358&mlfb=3VA1116-1AA32-0CC0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1116-1AA32-0CC0/alternatives.json"},"ai":{"faq":[{"question":"What is 3VA1116-1AA32-0CC0 used for?","answer":"It's a switch disconnector rated 160 A, 690 V AC / 500 V DC, used for load-break isolation in distribution panels, machine supply disconnects, or as a main switch where overcurrent protection is handled by a separate device upstream or downstream."},{"question":"Will 3VA1116-1AA32-0CC0 drop into a panel specified around 3VA1110-5EE32-0DC0?","answer":"Yes, the 3VA1116-1AA32-0CC0 shares the same 3VA1 frame dimensions — 76.2 mm width, 70 mm depth, 130 mm height — so it fits the same mounting cutout and DIN-rail footprint. The main difference is that the 3VA1116-1AA32-0CC0 is a switch disconnector (no overcurrent protection), while the 3VA1110-5EE32-0DC0 is a molded case circuit breaker with a TM220 release.
