The 4-pole design with ETU350 electronic trip unit gives you adjustable long-time (tr 0.5–17 s) and short-time (tsd 0.04–0.4 s) delay bands, plus N-conductor protection configurable to OFF, 50%, or 100% of the phase setting. The breaker holds its full 800 A rating up to 60 °C ambient. At 65 °C it derates to 767 A, and at 70 °C to 703 A — no headroom loss in a typical 40 °C panel, but worth checking if the enclosure sits near a heat source or in a non-conditioned space. The 3VA2580-7HN42-0AA0 measures 280 mm wide by 320 mm high by 120 mm deep — a standard footprint for a 4-pole 800 A MCCB in the SENTRON 3VA platform. No DIN-rail clip — this is a bolted-frame breaker sized for bolted busbar connection. ## Environmental limits The 10 000 mechanical endurance cycles (latching) cover the expected service life for a main breaker in a distribution panel — not a daily-switched load-break device, but a protective disconnecting means.","metaTitle":"Siemens 3VA2580-7HN42-0AA0 SENTRON MCCB, 800 A, 242 kA at 41","metaDescription":"Siemens SENTRON 3VA2580-7HN42-0AA0 molded case circuit breaker, 800 A rated current, 242 kA breaking capacity at 415 V, 4-pole, ETU350 trip unit, IP40 front.
