It carries an ETU320 LI trip unit — that's a microprocessor-based electronic release with long-time (L) and instantaneous (I) protection curves. The rated continuous current In is 630 A, with the overload protection Ir adjustable from 250 A to 630 A and the short-circuit pickup Ii settable between 1.5 and 9 times In. This unit ships with an integrated undervoltage release rated 120–127 V AC 50/60 Hz, plus an auxiliary switch changeover contact and a nut keeper kit for the mounting hardware. The ETU320 LI trip unit gives you field-adjustable long-time pickup (Ir) and instantaneous pickup (Ii), so one breaker frame covers a wide range of cable and load protection settings without swapping trip packs. The undervoltage release (120–127 V AC) drops the breaker on loss of control voltage, a common requirement for emergency-stop chains or undervoltage protection schemes. The auxiliary switch provides a remote status signal for the PLC or SCADA.","metaTitle":"Siemens 3VA2463-5HL32-0CB0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HL32-0CB0 IEC frame 630 circuit breaker, 3-pole, breaking capacity class M, Icu=55kA @ 415V, ETU320 LI trip unit, In=630A, Ir=250-630A, Ii=1.5-9x In.

The form factor, mounting, and terminal layout are identical; the delta is in the protection curve and the interrupting rating. Check the spec line yourself: the ETU320 LI is a two-function release (long-time + instantaneous), so if you need ground-fault (G) or short-time (S) protection, you'd step up to an ETU330 or ETU350 variant."},{"question":"Where can I buy 3VA2463-5HL32-0CB0 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution.
