The LSI trip gives you independent adjustment of long-time (Ir, 250–630 A), short-time (Isd, 1.5–9× Ir), and instantaneous (Ii, fixed at 9× In) protection, so you can coordinate selectivity downstream without sacrificing arc-flash coordination upstream. ## Integration notes The included universal release (24 V DC accessory) and up to 2 auxiliary switches allow remote tripping and status feedback — useful for a PLC-driven shutdown circuit or a motor control center (MCC) bucket. The nut keeper kit simplifies busbar connection in a multi-breaker lineup. The ETU350 is self-powered from the line side; no external control power is needed for the trip unit itself, though the shunt release does require the 24 V DC supply.","metaTitle":"Siemens 3VA2463-5HN32-0LB0 630A Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA2463-5HN32-0LB0 IEC frame 630 MCCB, 55kA breaking capacity at 415V, ETU350 LSI trip unit, 630A rated.
