The breaker's insulation voltage is rated at 800 V, and its breaking capacity reaches 440 kA at 240 V, 330 kA at 415/440 V, 220 kA at 500 V, and 52.5 kA at 690 V, giving it substantial fault-interrupting headroom across common industrial voltage levels. ## Breaking capacity and selectivity coordination At 415 V (common European industrial supply), the 330 kA rating still provides strong selectivity headroom against downstream breakers. For a 40 A frame, these are aggressive SCCR figures; the ETU320 release's adjustable trip settings let the engineer coordinate time-current curves with downstream devices rather than relying solely on the high instantaneous break. The 4-pole format (3 phases + neutral) fits European TN and TT systems where neutral switching is required; for a 3-pole-only panel, the 3VA2 family offers variants without the fourth pole.","metaTitle":"Siemens 3VA2040-8HL46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 440 k","metaDescription":"Siemens 3VA2040-8HL46-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 4-pole, ETU320 release, 440 kA breaking at 240 V.
