That thermal curve means it holds its full rating across most common panel ambient conditions — you only lose headroom above 50 °C, which is typical for a closed cabinet near process heat. Breaking capacity is specified at five voltage levels: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The breaker ships without undervoltage release, ground-fault monitoring, or communication module; it is a straight thermal-magnetic line-protection device, not a metering or remote-trip breaker. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for this class — it occupies one 3-module position on a DIN rail or direct-mount plate. The auxiliary switch block (3 auxiliary switches HQ) mounts on the side without increasing the pole pitch, so you can add status feedback without widening the footprint.","metaTitle":"Siemens SENTRON 3VA1080-3ED32-0AD0 MCCB, 80 A, 3-Pole, 70 mm","metaDescription":"Siemens SENTRON 3VA1080-3ED32-0AD0 molded case circuit breaker. 80 A rated current, 3-pole, 75.6 kA breaking at 240 V.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"Will 3VA1080-3ED32-0AD0 drop into a panel specified around 3VA1010-3ED36-0AA0?","answer":"Both are 3-pole SENTRON MCCBs with the same 76.2 mm width per pole, so the mounting footprint is identical. The 3VA1080-3ED32-0AD0 carries an 80 A rating versus the 3VA1010-3ED36-0AA0's different rating, so the thermal-magnetic trip curve differs. Physically it fits the same panel cutout and DIN rail position; no rewiring of the bus bars or lug positions is needed."},{"question":"What compliance documentation does Siemens provide for 3VA1080-3ED32-0AD0?","answer":"As a SENTRON series MCCB, standard compliance documentation includes IEC/EN 60947-2 certification. RoHS and REACH declarations are available from the manufacturer. The product is designed for line protection per its designation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1080-3ED32-0AD0","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/3VA1080-3ED32-0AD0 when reusing this data.
