It carries the ETU860 electronic trip unit configured for LSIG protection — long-time, short-time, instantaneous, and ground-fault — with an In of 630 A. Overload protection (Ir) is adjustable from 250 A to 630 A; short-circuit protection (Isd) from 0.6 to 9 times In, and instantaneous pickup (Ii) from 1.5 to 9 times In. Ground-fault protection is switchable, with pickup (Ig) from 0.2 to 1 times In and time delay (tg) from 0.05 to 0.8 seconds. The breaker ships with two auxiliary switches and one trip alarm switch. The ETU860's LSIG profile covers full-spectrum protection: long-time for cable/overload, short-time and instantaneous for bolted faults, and ground-fault for arcing or leakage paths. The adjustable ground-fault delay (0.05–0.8 s) allows coordination with downstream devices. Two auxiliary switches and one trip alarm switch provide status feedback for PLC or SCADA inputs.","metaTitle":"Siemens 3VA2463-5KQ32-0AH0 3VA2 IEC Frame 630, 55kA @ 415V,","metaDescription":"Siemens 3VA2463-5KQ32-0AH0 circuit breaker, 3VA2 IEC frame 630, breaking capacity class M Icu=55kA @ 415V, 3-pole, ETU860 LSIG, In=630A.
