It is built around the ETU350 trip unit configured for LSI protection — long-time, short-time, and instantaneous — with a rated current In of 630 A. Overload protection Ir is adjustable from 250 A to 630 A, short-time pickup Isd from 1.5 to 9 times Ir, and instantaneous pickup Ii fixed at 9 times In. The neutral conductor protection is selectable: OFF, 50%, or 100% of the phase current. The unit is designed for panel integration, typically on a mounting plate or within a switchgear enclosure, with the ETU350 providing local metering and event logging via the front interface. The LSI curve allows selective coordination with downstream breakers — the short-time delay band (Isd) can be set to ride through inrush without nuisance trips, while the instantaneous pickup (Ii) at 9x In clears hard faults fast. The adjustable neutral protection is useful for 4-wire systems where the neutral conductor may be undersized or where harmonic currents need to be managed.","metaTitle":"Siemens 3VA2463-7HN42-0DD0 Circuit Breaker, 630A, 110kA @ 41","metaDescription":"Siemens 3VA2463-7HN42-0DD0 IEC frame 630 circuit breaker, class C, 110kA @ 415V. 4-pole, ETU350 LSI, 630A.
