Size the upstream conductor and downstream load accordingly; the trip unit doesn't compensate for ambient inside the enclosure. ## Auxiliary contacts and trip alarm — what's on the side That's enough for a remote status signal and a separate alarm on fault trip without adding a module. ## Panel fit — dimensions and front IP Listed as current production — no phase-out notice on this code. That means it's a standard BOM line, not a last-time-buy scavenger hunt.","metaTitle":"Siemens 3VA2163-5HN32-0AH0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens 3VA2163-5HN32-0AH0 SENTRON molded case circuit breaker, 63 A rated, 187 kA breaking at 240 V, ETU350 release, 3-pole, active production, available to order against RFQ.","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","title":"3VA2163-5HN32-0AH0","Height":"181 mm","at 240 V":"187 kA","at 415 V":"121 kA","at 440 V":"121 kA","at 500 V":"79 kA","at 690 V":"4.25 kA","at 40 °C":"63 A","at 45 °C":"63 A","at 50 °C":"63 A","at 55 °C":"60.6375 A","at 60 °C":"58.275 A","at 65 °C":"55.9125 A","at 70 °C":"53.55 A","description":"circuit breaker 3VA2 IEC frame 160 breaking capacity class M Icu=55kA @ 415V 3-pole, line protection ETU350, LSI, In=63A overload protection Ir=25A...63A short-circuit protection Isd=1.5...10 x Ir, Ii=12 x In nut keeper kit 2 auxiliary switches HQ 1 trip alarm switch HQ","Trip indicator":"Yes","Number of poles":"3","Product version":"Line 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":"No","Phase failure detection":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"4 W","Auxiliary contact version":"2 auxiliary switches + 1 trip alarm switch HQ","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Rated continuous current Iu":"63 A","Rated insulation voltage Ui":"800 V","Of The Supplied Basic Switch":"3VA2163-5HN32-0AA0","Design of the auxiliary release":"Without auxiliary release","Ground fault monitoring version":"Without","Design of the overcurrent release":"ETU350","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"17","Adjustable response value time / tr min.":"0.5","Adjustable response value time / tsd max.":"0.4 s","Adjustable response value time / tsd min.":"0.02 s","Undervoltage Release With Leading Contact":"No","Product extension / optional / motor drive":"Yes","Adjustable response value current / Ir max.":"63 A","Adjustable response value current / li max.":"756 A","Adjustable response value current / li min.":"756 A","Adjustable response value current / lr min.":"25 A","Adjustable response value current / Isd max.":"630 A","Adjustable response value current / Isd min.":"95 A","Neutral conductors / upgradeable/retrofittable":"No","Number of CO contacts / for auxiliary contacts":"3","Protective function of the overcurrent release":"LSI","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AB12","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b27f8f8fa25a6619d6d76a928fe2e8a2.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=254632&mlfb=3VA2163-5HN32-0AH0"},"ai":{"faq":[{"question":"What is the breaking capacity of 3VA2163-5HN32-0AH0 at 415 V?","answer":"121 kA at 415 V, same as at 440 V.
