The ETU320 electronic trip unit supports LSIG protection (long-time, short-time, instantaneous, ground fault) with adjustable curves, so you coordinate selectively downstream without nuisance trips on inrush or welded-contact faults. Interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V — figures that clear bolted faults on a 2 MVA transformer secondary without cascading upstream. At 690 V it still breaks 9 kA, enough for a 690 V drive line-up in a steel mill. The 4-pole construction switches the neutral, required on IT or corner-grounded delta systems common in older mill distribution. ## Ambient derating and panel fit At 50 °C the continuous rating drops to 593 A; at 60 °C it's 557 A; at 70 °C it's 520 A. If your panel sits near a furnace or a drive cabinet that radiates heat, size the feeder for the actual ambient — the 630 A nameplate is only valid at 40 °C.","metaTitle":"Siemens 3VA2463-5HL42-0AA0 SENTRON MCCB, 630 A, 187 kA at 24","metaDescription":"Siemens 3VA2463-5HL42-0AA0 SENTRON molded case circuit breaker, 630 A rated current, 187 kA interrupting at 240 V, ETU320 trip unit, 4-pole, IP40 front.
