Its breaking capacity class H delivers Icu=85kA at 415V AC — sufficient for high-fault utility or transformer-fed main feeders in industrial switchboards. The ETU860 provides full LSIG protection: long-time pickup Ir adjustable 250-630A, short-time pickup Isd 0.6-9x In, instantaneous Ii 1.5-9x In, and ground-fault pickup Ig 0.2-1x In with time delay tg 0.05-0.8s. The shunt trip (left side, 208-277V AC 50/60Hz) allows remote tripping, and the included 1 auxiliary switch HP plus 1 trip alarm switch HP feed status back to a PLC or annunciator panel. The ETU860 LSIG trip unit is fully adjustable: Ir (long-time pickup) from 250A to 630A lets you match the cable or bus rating, Isd (short-time) from 0.6 to 9x In gives selective coordination with downstream breakers, and Ii (instantaneous) from 1.5 to 9x In handles high-inrush loads like motor starters. The ground-fault function (Ig 0.2-1x In, tg 0.05-0.8s) provides equipment protection on solidly-grounded systems; for N-conductor protection, an external current transformer can be added. The shunt trip operates on 208-277V AC control power — verify that your control voltage matches before wiring. ## Panel integration This is a fixed (non-withdrawable) 3-pole MCCB designed for bolted connection in a distribution panel or switchboard. It occupies the standard 3VA2 frame 630 footprint — check the Siemens mounting pattern and bus-bar drill plan before laying out the enclosure. The ETU860 is powered by internal current sensing; no external control power is needed for the trip unit itself. The shunt trip and auxiliary/trip alarm switches require wiring back to the control circuit. The breaker accepts line and load side lugs or bus-bar adapters; verify lug ampacity for 630A continuous current.","metaTitle":"Siemens 3VA2463-6KQ32-0KG0 Circuit Breaker, 630A, 85kA @ 415","metaDescription":"Siemens 3VA2463-6KQ32-0KG0 IEC frame 630 circuit breaker, 3-pole, ETU860 LSIG protection, 85kA breaking capacity at 415V, 630A rating.
