The LSI trip (Long-time, Short-time, Instantaneous) gives you adjustable overload (Ir from 250 A to 630 A), short-time pickup (Isd from 1.5 to 9x Ir), and a fixed instantaneous pickup at 9x In (5670 A). That lets you dial in coordination with downstream feeders without oversizing the breaker. The 4-pole configuration handles three-phase plus neutral, and the neutral protection is adjustable — OFF, 50%, or 100% of the phase rating — which matters for 4-wire systems where the neutral may carry harmonic currents. The built-in undervoltage release (24 V DC) lets a safety circuit or emergency-stop chain drop the breaker without a separate shunt-trip module.","metaTitle":"Siemens 3VA2463-5HN42-0BH0 IEC Breaker, 630 A, 55 kA @ 415 V","metaDescription":"Siemens 3VA2463-5HN42-0BH0 IEC frame 630 circuit breaker, 55 kA breaking capacity @ 415 V, ETU350 LSI trip, 630 A rated current.
