It ships with a TM240 thermal-magnetic trip unit, rated In=400 A, adjustable overload Ir from 280 A to 400 A, and short-circuit pickup Ii adjustable 5 to 10 times In. Two built-in auxiliary changeover switches are included, plus a nut keeper kit for secure panel mounting. The TM240 trip unit gives you a thermal curve for overloads and a magnetic instantaneous for shorts; the adjustable Ir (280–400 A) lets you fine-tune the continuous current to match the downstream load, not just the frame. The Ii range of 5–10× In (2,000–4,000 A) covers motor-start inrush or feeder protection without nuisance trips. The 3-pole footprint fits a typical 400 A frame cutout; auxiliary switches are factory-installed, so no add-on module occupies adjacent DIN space. Verify gland-plate clearance for the line and load lugs — frame 400 breakers usually require 70–95 mm² cable terminations.","metaTitle":"3VA1340-5EF32-0AB0 Siemens 3VA1 IEC Frame 400, 55kA @ 415V,","metaDescription":"Siemens 3VA1340-5EF32-0AB0 circuit breaker, IEC frame 400, class M, Icu=55kA @ 415V, 3-pole, TM240, In=400A, Ir=280-400A, Ii=5-10xIn.
