The TM240 ATAM trip unit delivers thermal-magnetic overload protection with an adjustable Ir range from 280 A to 400 A (the In rating), and a short-circuit pickup Ii adjustable from 5 to 10 times In. ## Deployment context: where this breaker fits The 3VA1 frame bolts into a standard distribution panel or switchboard — it's a fixed-mount MCCB, not a plug-in unit, so plan for bus-bar drilling and torque-specified terminations. The included nut keeper kit for DC Power OEM in China suggests this variant was configured for a specific OEM integration; verify the nut keeper thread and torque spec if you're replacing an existing unit in a panel built for that OEM.","metaTitle":"Siemens 3VA1340-6EF42-0AA0-ZD00 Circuit Breaker, 400A, 70kA","metaDescription":"Siemens 3VA1340-6EF42-0AA0-ZD00 IEC frame 400 breaker, 4-pole, 70kA Icu @ 415V, TM240 ATAM overload 280-400A, current lifecycle stage.

No pin-compatible direct drop-in is listed as an official successor; for a parametric match, look for another 3VA1 IEC frame 400 4-pole breaker with class H breaking capacity and a TM240 trip unit.
