The TM240 thermal-magnetic trip unit gives it a fixed 400 A continuous current rating (In) with adjustable overload protection (Ir) from 280 A to 400 A, and short-circuit pickup (Ii) adjustable from 5 to 10 times In. On a 400 A feeder, set Ir at 320 A for a 320 A continuous load and Ii at 8x (3200 A) to ride through motor inrush without nuisance trips. Also included: two changeover auxiliary switches for remote status indication. ## Panel Integration — DIN-Rail Mount, Fill Factor, and Auxiliary Wiring Mounts on standard DIN rail per IEC 60715. The 3VA1 frame 400 footprint is compact for its 400 A rating — roughly 105 mm wide per pole — so a 3-pole unit occupies about 315 mm of rail width. The undervoltage release has its own 2-wire connection — verify polarity if the coil is AC, no polarity if it is the DC variant (this one is AC, so polarity irrelevant).","metaTitle":"Siemens 3VA1340-5EF32-0DH0 Circuit Breaker, 55kA @ 415V, 400","metaDescription":"Siemens 3VA1340-5EF32-0DH0 IEC frame 400 MCCB, 55kA Icu @ 415V, TM240 thermal-mag trip, 400A In, Ir 280-400A, Ii 5-10x In.

If you need the same accessories, the order code is unique; a bare breaker plus separate accessory kit is possible but adds panel wiring labor."},{"question":"Where can I buy 3VA1340-5EF32-0DH0?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
