Thermal derating is published per degree: full 100 A up to 50 °C, then 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. The 105 mm width is standard for a 3-pole 100 A frame in the 3VA2 series; it occupies three 35 mm DIN-rail modules worth of panel space if using an adapter base, or it bolts directly to a mounting plate via the four corner slots. ## Trip Unit and Auxiliaries The ETU350 overcurrent release is a microprocessor-based unit with adjustable thermal and magnetic settings — typical for feeder or main breaker duty where coordination with downstream breakers matters. Power dissipation is 13.5 W maximum; factor that into the enclosure thermal calculation. The 20 000-cycle mechanical endurance is typical for a 100 A frame — fine for infrequent switching (main breaker duty), not for daily motor starting.","metaTitle":"Siemens 3VA2010-5HN32-0KA0 SENTRON MCCB, 100A, 3-Pole, ETU35","metaDescription":"Siemens 3VA2010-5HN32-0KA0 SENTRON molded case circuit breaker. 100A rated, 3-pole, ETU350 release.
