It carries an ETU350 LSI electronic trip unit rated at 630 A, with overload protection adjustable from 250 A to 630 A and short-circuit protection set at 1.5–9x Ir, plus instantaneous pickup at 9x In. The neutral conductor protection is field-selectable (OFF, 50%, or 100% of phase protection). The ETU350 LSI trip unit gives you selective coordination flexibility: the LSI (Long-time, Short-time, Instantaneous) profile lets you set short-time delay and pickup to ride through downstream faults, keeping your feeder alive while a branch breaker clears. The adjustable neutral protection (OFF/50%/100%) is useful for 4-wire systems where neutral loading varies, common in commercial or mixed-load panels. The shunt trip accessory (208–277 V AC / 220–250 V DC) allows remote tripping from an emergency stop circuit or a fire-alarm relay — a standard requirement in safety-instrumented systems.","metaTitle":"Siemens 3VA2463-5HN42-0KB0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HN42-0KB0 IEC frame 630 MCCB, 55kA breaking capacity at 415V, ETU350 LSI trip unit, 630A rated.
