The interrupting capacity climbs to 187 kA at 240 V and stays at 121 kA through 440 V; at 690 V it still clears 4.25 kA. That's a lot of fault energy for a 100 A frame, meaning it's sized for high-available-fault panels where a standard MCCB would weld itself shut. Thermal derating is published all the way to 70 °C ambient: it holds 100 A flat from 40 °C to 50 °C, then drops to 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. The breaker occupies 105 mm width, 181 mm height, and 86 mm depth. The depth matters when you're up against a gland plate or a shallow enclosure door; 86 mm leaves room for cable bends and the undervoltage release module that comes fitted on this variant. Communication function and other measurement functions are present, so this breaker can report status and energy data back to a BMS or PLC without a separate metering module. ## What's on the van — field-service perspective If you're swapping this into an existing panel, the key gotcha is the undervoltage release: it needs a control voltage to hold the breaker closed. No control power means the breaker stays tripped, which is the intended behaviour but can surprise someone who expects a plain thermal-magnetic that stays latched. The ETU850 is programmable via the front keypad or software, so you can adjust long-time, short-time, instantaneous, and ground-fault settings without swapping trip units. The 20 000 mechanical endurance cycles mean it's rated for switching duty, not just backup protection — it'll handle regular load-break operations on a production line.","metaTitle":"Siemens 3VA2110-5KP32-0CC0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2110-5KP32-0CC0 molded case circuit breaker, 100 A rated continuous current, 187 kA interrupting at 240 V, ETU850 release, undervoltage trip, active production.","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":"79 kA","at 690 V":"4.25 kA","at 40 °C":"100 A","at 45 °C":"100 A","at 50 °C":"100 A","at 55 °C":"96.25 A","at 60 °C":"92.5 A","at 65 °C":"88.75 A","at 70 °C":"85 A","Trip indicator":"No","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":"Yes","Communication Function":"Yes","Phase failure detection":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","Power loss [W] / maximum":"12.5 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","Of The Supplied Basic Switch":"3VA2110-5KP32-0AA0","Design of the auxiliary release":"Undervoltage release (UVR)","Ground fault monitoring version":"Without","Of The Integrated Auxiliary Trip":"3VA9608-0BB24","Design of the overcurrent release":"ETU850","Protection class IP / on the front":"IP40","Reference code / acc. to DIN EN 81346-2":"Q","Adjustable response value time / tr max.":"25","Adjustable response value time / tr min.":"0.5","Adjustable response value time / tsd max.":"0.5 s","Adjustable response value time / tsd min.":"0.05 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 / li max.":"1 200 A","Adjustable response value current / li min.":"150 A","Adjustable response value current / lr min.":"40 A","Adjustable response value current / Isd max.":"1 000 A","Adjustable response value current / Isd min.":"60 A","Neutral conductors / upgradeable/retrofittable":"Yes","Number of CO contacts / for auxiliary contacts":"2","Protective function of the overcurrent release":"LSI","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=148659&mlfb=3VA2110-5KP32-0CC0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA2110-5KP32-0CC0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2110-5KP32-0CC0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2110-5KP32-0CC0 when reusing this data.
