It carries TM240 line protection and ATAM — meaning the thermal-magnetic trip unit is fixed at 240A thermal pickup, with adjustable overload protection from 280A to 400A (Ir) and short-circuit protection set from 5 to 10 times In (Ii). The adjustable Ir (280–400A) lets you match the breaker to the actual load current, not just the frame size — useful when the connected load is below 400A and you want tighter overload protection.","metaTitle":"Siemens 3VA1340-4EF32-0AA0-ZD00 Circuit Breaker, 400A, 36kA","metaDescription":"Siemens 3VA1340-4EF32-0AA0-ZD00 circuit breaker, 3VA1 IEC frame, 400A, Icu=36kA @ 415V, 3-pole, TM240, ATAM, overload Ir=280-400A, short-circuit Ii=5-10xIn.
