The ETU850 trip unit gives you LSI protection: Long-time pickup Ir adjustable 250A through 630A, short-time pickup Isd from 0.6x to 9x In, and instantaneous Ii from 1.5x to 9x In. That range covers motor-start inrush and transformer magnetizing peaks without nuisance tripping — set the Isd delay to coordinate with downstream breakers. ## Line-down fit and auxiliaries This unit ships with two auxiliary changeover switches and one trip alarm changeover switch pre-installed — no separate order for alarm contacts. Neutral conductor protection is optional via an external current transformer, up to 160% of In. Mounts on the standard DIN rail or bolted into the switchboard. The 3VA2 frame footprint matches existing 3VA1 cutouts in most Siemens panels — verify gland plate clearance if retrofitting into a legacy cubicle.","metaTitle":"Siemens 3VA2463-5KP32-0AL0 630A Circuit Breaker, 55kA @ 415V","metaDescription":"Siemens 3VA2463-5KP32-0AL0 IEC frame 630, 3-pole, 55kA Icu @ 415V, ETU850 LSI, 630A.

That's enough for most industrial main feeders — you can coordinate downstream breakers rated lower (say 25kA or 36kA) as long as the let-through energy stays within their ratings."},{"question":"What auxiliary contacts come on this breaker?","answer":"It ships with two auxiliary changeover switches and one trip alarm changeover switch — all pre-installed.
