That means it holds its 25 A rating in a warm enclosure without a sizing penalty. The N-conductor protection is configurable to OFF or 100% of the phase rating. Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. Power dissipation is only 0.84 W per pole at rated current — negligible for enclosure thermal calculations. The 3VA2025-6HN46-0AA0 measures 140 mm wide, 181 mm high, and 86 mm deep — a standard 4-pole MCCB footprint that fits SENTRON 3VA2 panelboards and distribution boards. The trip indicator is also absent — fault status is read from the handle position and the ETU's local LED. If you need those options, look at the 3VA2 family with the appropriate suffix codes.","metaTitle":"Siemens 3VA2025-6HN46-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU35","metaDescription":"Siemens SENTRON 3VA2025-6HN46-0AA0 molded case circuit breaker, 25 A rated, 4-pole, ETU350 electronic trip unit.
