Rated In = 400 A, with overload protection (Ir) adjustable from 160 A to 400 A. That range covers large motor loads — think 200+ kW pumps or compressors on a 400 V line — and the LSIG profile (long-time, short-time, instantaneous, ground-fault) gives you four-quadrant protection curves. Short-circuit pickup (Isd) is settable from 1.2 to 15× In, and instantaneous (Ii) from 3 to 15× In, so you can shape the curve to ride through motor inrush without nuisance trips. Ground-fault protection (Ig) is adjustable 0.2 to 1× In with a time delay (tg) of 0.05 to 0.8 s, which helps coordinate with downstream feeders. The 3-pole frame 630 footprint is standard for Siemens 3VA2 switchgear — it occupies the same cutout as other frame-630 breakers, so a panel layout designed for a 3VA2 630A frame accepts this unit without re-drilling gland plates.","metaTitle":"Siemens 3VA2440-5MQ32-0AB0 Circuit Breaker, 55kA @ 415V, 400","metaDescription":"Siemens 3VA2440-5MQ32-0AB0 IEC frame 630 circuit breaker, 55kA breaking capacity @ 415V, 3-pole, ETU860M LSIG motor protection, In=400A.
