The ETU350 electronic trip unit gives you LSI protection: long-time (Ir adjustable 250–630 A), short-time (Isd 1.5–9× Ir), and instantaneous (Ii fixed at 9× In). That adjustable Ir range means you size the breaker to the actual load, not the frame; set Ir to match the downstream conductor ampacity. ## Built-in accessories save a panel-build step This order code ships with a shunt trip fitted on the left side, rated 208–277 V AC 50/60 Hz and 220–250 V DC, plus one auxiliary switch. The auxiliary switch signals breaker position (open/closed) back to a PLC or status lamp. Both are factory-installed, so they land on the DIN rail as a single unit.","metaTitle":"Siemens 3VA2463-5HN32-0KF0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HN32-0KF0 IEC frame 630 circuit breaker, 55kA breaking capacity @ 415V, ETU350 LSI protection, 630A, shunt trip.
