That's the high-capacity variant for this frame size, sized for main feeders or large motor branch circuits where fault current runs high. The TM240 thermal-magnetic trip unit gives you adjustable overload protection from 280 A to 400 A (Ir), and short-circuit pickup (Ii) adjustable from 5 to 10 times In. That range covers motor starting inrush and transformer magnetizing current without nuisance tripping. Factory-fitted: two changeover auxiliary switches (H) and one trip-alarm switch. The 3VA1 family uses a common footprint across frame 400 breakers, so if you're replacing an older 3VA1 unit, the bus-bar and lug kit positions are identical. The TM240 trip unit is field-adjustable without removing the breaker cover — Ir dial and Ii rotary switch are accessible from the front. No need to pull the breaker out of the panel for setting changes.","metaTitle":"Siemens 3VA1340-6EF32-0AH0 Circuit Breaker, 400A, 70kA @ 415","metaDescription":"Siemens 3VA1340-6EF32-0AH0 IEC frame 400 circuit breaker, 3-pole, 70kA breaking capacity @ 415V, TM240 trip unit, 400A rated.
