For a 480 V distribution panel, the 187 kA figure at 440 V is the applicable benchmark — well above typical available fault currents in most industrial switchboards, provided the upstream transformer impedance is within normal ranges. The 3VA2025-6HN36-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without gland-plate surprises. Power loss is 0.84 W maximum — negligible for thermal budgeting inside a crowded panel.","metaTitle":"Siemens 3VA2025-6HN36-0AA0 SENTRON MCCB, 25A, 3-Pole, ETU350","metaDescription":"Siemens 3VA2025-6HN36-0AA0 SENTRON molded case circuit breaker, 25A rated, 3-pole, ETU350 electronic trip unit.
