The ETU330 is a basic electronic trip unit — no communication module, no voltage trigger, no undervoltage release on this variant. Ground-fault monitoring uses summation current formation on the L-conductor, so it picks up residual current without a separate GFCI module. The front carries IP40 protection, meaning it's splash-resistant in a closed panel but not washdown-rated. ## Footprint and panel fit At 86 mm deep, 105 mm wide, and 181 mm tall, this 3-pole MCCB fits the standard SENTRON 3VA2 mounting footprint. The optional motor drive (product extension available) adds length but stays within the same mounting hole pattern.","metaTitle":"Siemens 3VA2025-8HM36-0AA0 SENTRON MCCB, 25 A, 440 kA at 240","metaDescription":"Siemens 3VA2025-8HM36-0AA0 SENTRON molded case circuit breaker, 3-pole, 25 A, ETU330 trip unit, 440 kA at 240 V.

The 3VA2025 is a 25 A line-protection variant with an ETU330 trip unit; the 3VA2140 is a higher-current variant.
