The 80 A rating holds flat from 40 °C to 50 °C, then derates to 74 A at 70 °C; if your panel runs hot, you lose about 6 A off the top. The 3VA1080-2ED36-0DH0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON distribution panels or standalone enclosures without re-drilling. The undervoltage release (UVR) is built in, so you do not need a separate shunt-trip module for loss-of-voltage protection. Two auxiliary contacts and a trip alarm switch give you feedback for status monitoring or interlocking.","metaTitle":"3VA1080-2ED36-0DH0 SENTRON MCCB, 80 A, 52.5 kA at 240 V","metaDescription":"SENTRON 3VA1080-2ED36-0DH0 molded case circuit breaker, 80 A rated current, 52.5 kA breaking capacity at 240 V, 3-pole, undervoltage release, auxiliary switches, current production","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","Maximum":"0 A","Minimum":"0 A","at 240 V":"52.5 kA","at 415 V":"32 kA","at 440 V":"13.6 kA","at 500 V":"7.5 kA","at 690 V":"7.5 kA","at 40 °C":"80 A","at 45 °C":"80 A","at 50 °C":"80 A","at 55 °C":"78 A","at 60 °C":"77 A","at 65 °C":"75 A","at 70 °C":"74 A","Depth [In]":"2.76 in","Width [In]":"3 in","Height [In]":"5.12 in","Trip Indicator":"Yes","Number Of Poles":"3","Voltage Trigger":"No","lifecycle_stage":"current","Product Brand Name":"SENTRON","Product Designation":"Molded case circuit breaker","Undervoltage Release":"Yes","Design Of The Product":"Line protection","Communication Function":"No","During Storage / Maximum":"80 °C","During Storage / Minimum":"-40 °C","power loss [W] / maximum":"21.7 W","During Operation / Maximum":"70 °C","During Operation / Minimum":"-25 °C","Other Measurement Function":"No","Of The Supplied Basic Switch":"3VA10802ED360AA0","Design Of The Auxiliary Switch":"2 auxiliary switches + 1 trip alarm switch HQ","Design Of The Auxiliary Release":"undervoltage release (UVR)","Ground-Fault Monitoring Version":"Without","Insulation Voltage / Rated Value":"800 V","Design Of The Overcurrent Release":"TM210","Design Of Short-Circuit Protection":"For switching power values in DC networks, see the 3VA molded case circuit breaker device manual; link to be found under Service & Support in the last chapter","protection class IP / on the front":"IP40","Of The Integrated Auxiliary Trip Unit":"3VA9608-0BB25","Product Function / Grounding Protection":"No","operating voltage / at AC / rated value":"690 V","operating voltage / at DC / rated value":"500 V","reference code / according to IEC 81346-2":"Q","Product Extension / Optional / Motor Drive":"No","Protection Function Of The Overcurrent Release":"LI","number of CO contacts / for auxiliary contacts":"3","Of The Integrated Auxiliary Switch/Alarm Switch":"3VA9988-0AB12","Switching Capacity Class Of The Circuit Breaker":"B","Mechanical Service Life (Operating Cycles) / Typical":"20 000","Type Of Electrical Connection / For Main Current Circuit":"box terminal on both sides","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=61026&mlfb=3VA1080-2ED36-0DH0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3VA1080-2ED36-0DH0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3VA1080-2ED36-0DH0?","answer":"This breaker is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time."},{"question":"What is the breaking capacity of 3VA1080-2ED36-0DH0 at 415 V?","answer":"It breaks 32 kA at 415 V, which covers most industrial distribution panels in 400 V systems."},{"question":"Does 3VA1080-2ED36-0DH0 include an undervoltage release?","answer":"Yes, it comes with a built-in undervoltage release (UVR) — no separate shunt-trip module needed for loss-of-voltage protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1080-2ED36-0DH0","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/3VA1080-2ED36-0DH0 when reusing this data.
