Power loss is listed at 10 W maximum, which is modest for a 100 A frame and leaves headroom in a crowded panel's thermal budget. The 3VA2110-5MQ32-0AC0 measures 105 mm wide, 181 mm high, and 86 mm deep (4.1 in × 7.1 in × 3.4 in). The 86 mm depth is shallow enough for a 200 mm enclosure depth with room for wiring gutters; the 105 mm width is the same as other 3-pole 3VA frames, so a panel laid out for a 100 A SENTRON MCCB accepts this unit without re-spacing the DIN rail.","metaTitle":"Siemens 3VA2110-5MQ32-0AC0 MCCB, 100 A, 3-Pole, Motor Protec","metaDescription":"Siemens SENTRON 3VA2110-5MQ32-0AC0 molded case circuit breaker, 100 A rated continuous current, 3-pole motor protection version with communication function and phase failure detect","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Molded Case Circuit Breakers (MCCB)"],"specifications":{"Depth":"86 mm","Width":"105 mm","Height":"181 mm","at 240 V":"187 kA","at 415 V":"121 kA","at 440 V":"121 kA","at 500 V":"76 kA","at 690 V":"3.8 kA","at 40 °C":"100 A","at 45 °C":"100 A","at 50 °C":"100 A","at 55 °C":"100 A","at 60 °C":"100 A","at 65 °C":"100 A","at 70 °C":"100 A","Depth [in]":"3.4 in","Width [in]":"4.1 in","Height [in]":"7.1 in","Trip indicator":"No","Number of poles":"3","Product version":"Motor protection","Voltage trigger":"No","lifecycle_stage":"current","Product brand name":"SENTRON","Product designation":"Molded case circuit breaker","Latching - endurance":"20 000","Undervoltage Release":"No","Communication Function":"Yes","Phase failure detection":"Yes","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"10 W","Auxiliary contact version":"2 auxiliary switches HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"Yes","Rated continuous current Iu":"100 A","Rated insulation voltage Ui":"800 V","Design of the auxiliary release":"Without auxiliary release","Ground fault monitoring version":"Summation current formation L-conductor","Design of the overcurrent release":"ETU860M","Protection class IP / on the front":"IP40","Operating power / at AC-3 / at 230 V":"30 000 W","Operating power / at AC-3 / at 400 V":"55 000 W","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"25","Adjustable response value time / tr min.":"3","Adjustable response value time / tsd max.":"0 s","Adjustable response value time / tsd min.":"0 s","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Adjustable response value current / Ir max.":"100 A","Adjustable response value current / lg max.":"100 A","Adjustable response value current / lg min.":"20 A","Adjustable response value current / li max.":"1 500 A","Adjustable response value current / li min.":"300 A","Adjustable response value current / lr min.":"40 A","Adjustable response value current / tg max.":"0.8 s","Adjustable response value current / tg min.":"0.05 s","Adjustable response value current / Isd max.":"1 500 A","Adjustable response value current / Isd min.":"120 A","Ground fault protection can be switched ON/OFF":"Yes","Neutral conductors / upgradeable/retrofittable":"No","Number of CO contacts / for auxiliary contacts":"2","Protective function of the overcurrent release":"LSIG","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AA12","Switching capacity class of the circuit breaker":"M","Max. rated operational current of the frame size":"160 A","Max. rated operational voltage Ue with AC 50/60Hz":"690 V","Type of electrical connection / for main current circuit":"Lug terminal","Arrangement of electrical connectors / for main current circuit":"Front terminal","Type of connectable conductor cross-section, connection screw, width x thickness , max.":"25 x 8.5","Type of connectable conductor cross-section, connection screw, width x thickness , min.":"13 x 1 mm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/83eff65c44469ff46b70582785c85926.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1361572&mlfb=3VA2110-5MQ32-0AC0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2110-5MQ32-0AC0/alternatives.json"},"ai":{"faq":[{"question":"Will 3VA2110-5MQ32-0AC0 drop into a panel specified around 5SQ2370-2YA05 without rewiring?","answer":"Not without checking the auxiliary contact wiring and communication bus.
