The ETU550 electronic trip unit gives you LSI protection: long-time (Ir adjustable 250–630 A), short-time (Isd 0.6–9× In), and instantaneous (Ii 1.5–9× In). That adjustability lets you coordinate selectively with downstream breakers on a motor control center or feeder panel, so only the faulted branch trips. This breaker mounts in a standard distribution panel or switchboard on a 3VA2 mounting plate. The shunt trip (left side, 110–127 V AC/DC) lets a remote emergency-stop or fire-alarm relay open the breaker without a manual trip — common in furnace or conveyor-line safety circuits. The description also notes provision for N-conductor protection via an external current transformer, up to 160 % of the phase rating, which matters if you are feeding a 3-phase + N panelboard where the neutral can carry harmonic current.","metaTitle":"Siemens 3VA2463-5JP32-0JJ0 Circuit Breaker, 630A, Icu=55kA @","metaDescription":"Siemens 3VA2463-5JP32-0JJ0 circuit breaker, 3VA2 IEC frame 630, breaking capacity class M, Icu=55kA @ 415V, 3-pole, ETU550 LSI protection, In=630A.
