The breaker carries an ETU850 electronic trip unit with LSI protection: long-time (L) overload protection adjustable from Ir=160A to 400A, short-time (S) short-circuit protection with Isd adjustable 0.6 to 10x In, and instantaneous (I) protection adjustable 1.5 to 10x In. This gives selectivity coordination downstream — you can set the S-curve to ride through motor inrush while still tripping fast on a bolted fault. ## Integration Notes The 3VA2 frame accepts plug-in accessories (auxiliary switches, shunt trips, undervoltage releases) without removing the breaker from the bus. Comes with 2 auxiliary switch changeover contacts built in — that's enough for a remote status signal and a local indicator without adding an external aux block.","metaTitle":"Siemens 3VA2340-7KP32-0AB0 3VA2 IEC Frame 400, 110kA @ 415V","metaDescription":"Siemens 3VA2340-7KP32-0AB0 circuit breaker, 3VA2 IEC frame 400, Icu=110kA @ 415V, 3-pole, ETU850 LSI protection, In=400A.
