It carries the ETU850 electronic trip unit configured for LSI protection — long-time (Ir), short-time (Isd), and instantaneous (Ii) — with the continuous current rating In fixed at 630 A. The overload protection Ir is adjustable from 250 A to 630 A, the short-time pickup Isd from 0.6 to 9 times In, and the instantaneous pickup Ii from 1.5 to 9 times In. Neutral conductor protection is adjustable from OFF up to 100% of the phase setting. A nut keeper kit is included for secure mounting. For a 630 A frame, the adjustable Ir from 250 A to 630 A lets you match the thermal protection to the actual load cable or busway rating, not the frame size. The Isd and Ii ranges (0.6–9× In and 1.5–9× In respectively) give selectivity headroom downstream — you can set the short-time pickup above the let-through of feeder breakers to avoid nuisance tripping on motor-start inrush. The neutral protection adjustment (OFF to 100%) is useful on 4-wire systems where the neutral conductor may be undersized relative to the phases. ## Deployment context This breaker mounts in a standard IEC distribution panel or switchboard — the nut keeper kit supplied secures it against vibration on the mounting plate. The undervoltage release (208–230 V AC) provides automatic trip on loss of control voltage, which is typical for emergency-stop circuits or mains-monitoring schemes in industrial power distribution.","metaTitle":"Siemens 3VA2463-6KP42-0DD0 Circuit Breaker, 630A, 85kA @ 415","metaDescription":"Siemens 3VA2463-6KP42-0DD0 IEC frame 630 circuit breaker, breaking capacity class H Icu=85kA @ 415V, 4-pole, ETU850 LSI protection, In=630A.
