Breaking capacity is voltage-dependent: 242 kA at 240 V AC, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. N-conductor protection is adjustable: OFF, 50%, or 100% of the phase rating. That is unusual; many MCCBs start tapering above 40 °C. The 3VA2 keeps its full 250 A up to 70 °C, which simplifies coordination studies in hot environments. Front protection is IP40 — fine for indoor switchgear but not washdown zones. Dimensions: 248 mm high, 184 mm wide, 110 mm deep. The 184 mm width is the 4-pole frame; verify the panel cutout matches before committing the BOM line. Maximum power loss is 37.5 W — a figure to factor into enclosure thermal calculations, especially in multi-breaker assemblies.","metaTitle":"Siemens 3VA2325-6HL42-0AA0 SENTRON MCCB, 250 A, 4-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2325-6HL42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, ETU320 electronic trip unit.
