The ETU350M trip unit provides LSI protection (long-time, short-time, instantaneous) with overload protection Ir adjustable from 320 A to 800 A and short-circuit protection Isd adjustable from 3 to 15 times Ir, plus a fixed instantaneous pickup Ii=15 x In. This is a motor-protection breaker, so the LSI curve is shaped to ride through motor inrush while clearing a bolted fault fast. The release is wired in series with the 24 V DC control supply; if that supply fails, the breaker opens immediately. The 3VA2 frame 1000 is a bolted-front connection breaker, not a plug-in unit — expect bus-bar or cable lugs on the line and load sides. The nut keeper kit (included in the order code suffix) retains the terminal nuts during installation, a small time-saver in a crowded enclosure. The undervoltage release adds a pair of control wires to the 24 V DC bus; plan for a dedicated fuse or breaker on that circuit per Siemens wiring guidelines.","metaTitle":"Siemens 3VA2580-7MN32-0BL0 Circuit Breaker, 800 A, 110 kA @","metaDescription":"Siemens 3VA2580-7MN32-0BL0 IEC frame 1000 MCCB, 3-pole, 800 A, Icu=110 kA @ 415 V, ETU350M LSI trip, undervoltage release 24 V DC.

That is the maximum short-circuit current the breaker can safely interrupt once at that voltage — it governs whether this breaker coordinates with upstream protective devices in a fault scenario. For motor circuits, the LSI trip unit's adjustable Ir (320–800 A) and Isd (3–15 x Ir) let you tune the curve to the motor's locked-rotor current without nuisance tripping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2580-7MN32-0BL0","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/3VA2580-7MN32-0BL0 when reusing this data.
