It carries a breaking capacity class M rating of Icu=55kA @ 415V, meaning it can safely interrupt fault currents up to that level on a 415 V network without upstream cascading — critical for selective coordination in a distribution panel. The electronic ETU320 LI trip unit provides adjustable overload protection (Ir) from 160 A to 400 A and short-circuit protection (Ii) from 1.5 to 12 times the rated current In=400A. This adjustability lets the breaker be sized precisely to the downstream load without changing the frame or the breaker body. Factory-fitted accessories include an undervoltage release rated 208-230 V AC 50/60 Hz and an auxiliary switch — both mounted and wired inside the breaker, saving panel space versus field-installed add-ons. ## Deployment Context The 55 kA @ 415 V breaking capacity suits main or feeder breaker duty in industrial switchgear where high fault currents are expected.","metaTitle":"Siemens 3VA2440-5HL32-0DB0 Circuit Breaker, 400A, 55kA @ 415","metaDescription":"Siemens 3VA2440-5HL32-0DB0 IEC frame 630 MCCB, 3-pole, 400A, Icu=55kA @ 415V, ETU320 LI trip unit.
