It uses an ETU350 LSI electronic trip unit with adjustable overload protection Ir = 40…100 A, short-circuit protection Isd = 1.5…10 × Ir, and instantaneous protection Ii = 12 × In. The neutral conductor protection is adjustable (OFF, 50%, 100%). The 55 kA Icu at 415 V places this breaker in the medium breaking capacity class (class M), sized for industrial distribution panels where fault currents can reach that level — typical for transformer-fed switchboards in a factory. The ETU350 LSI trip unit provides selective coordination with downstream breakers: the long-time (L) band handles overloads, the short-time (S) band with adjustable delay allows downstream devices to clear a fault first, and the instantaneous (I) band catches high-magnitude faults. The adjustable neutral protection (OFF, 50%, 100%) suits 4-wire systems where neutral current monitoring is required by local code. ## Undervoltage release integration The release is factory-installed, so no field wiring of a separate accessory is needed.","metaTitle":"Siemens 3VA2110-5HN42-0DA0 Circuit Breaker, 100A, 55kA @ 415","metaDescription":"Siemens 3VA2110-5HN42-0DA0 IEC frame 160 MCCB, 4-pole, 100A, ETU350 LSI, 55kA breaking capacity @ 415V.
