The thermal-magnetic trip unit is a TM220 (ATFM) with In = 400 A. Overload protection (Ir) adjusts from 280 A to 400 A; short-circuit protection (Ii) is fixed at 10 × In. The 100% N-conductor protection means the neutral pole is fully rated — no derating needed for unbalanced loads or harmonic-rich circuits common in DC Power OEM builds. This variant includes a nut keeper kit and is specified for DC Power OEM in China. The nut keeper kit simplifies panel mounting by retaining the mounting nuts during installation — a small time-saver on repetitive builds.","metaTitle":"Siemens 3VA1340-4GE42-0AA0-ZD00 Circuit Breaker, 400A, 36kA","metaDescription":"Siemens 3VA1340-4GE42-0AA0-ZD00 IEC frame 400 breaker, class S, Icu=36kA @ 415V, 4-pole, TM220, In=400A, Ir=280-400A, Ii=10xIn.
