The ETU350 electronic trip unit gives LSI protection: long-time (Ir adjustable 250 A to 630 A), short-time (Isd 1.5 to 9× Ir), and instantaneous (Ii fixed at 9× In). That selectivity lets you coordinate downstream breakers without nuisance tripping on motor inrush or transformer energization. The ETU350's LSI curve is field-adjustable — Ir covers 250 A to 630 A, so a single frame size handles multiple load calibers. The built-in auxiliary switch (changeover H) and trip alarm switch (changeover) give the PLC or BMS a positive status signal without an add-on module.","metaTitle":"Siemens 3VA2463-5HN32-0AK0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HN32-0AK0 IEC frame 630 circuit breaker, 55kA @ 415V breaking capacity, ETU350 LSI protection, 630A rated current.
