Maximum power dissipation is 48 W at full load — relevant for enclosure thermal calculations when grouping multiple breakers. ## Frame Dimensions and Panel Fit The breaker measures 181 mm high × 140 mm wide × 86 mm deep — a standard 4-pole MCCB footprint that fits Siemens 3VA switchboard and distribution panel cutouts.","metaTitle":"Siemens 3VA2225-5HN42-0KA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens 3VA2225-5HN42-0KA0 SENTRON molded case circuit breaker, 250 A rated continuous current, 4-pole, ETU350 release, 187 kA at 240 V.
