That rating places it squarely in high-fault-current applications — think large motor control centers, transformer secondaries, or main feeders in industrial switchgear where available fault current exceeds 50 kA. The 4-pole construction with adjustable neutral protection (OFF, 50%, 100%) suits it for TN-S or TT systems where the neutral needs its own overload and short-circuit element. ## ETU320 LI trip unit — the adjustable window The electronic trip unit is an ETU320 with LI characteristic — long-time (overload) and instantaneous (short-circuit) protection. Overload pickup Ir is adjustable from 250 A to 630 A in steps, so the same breaker frame covers a wide range of cable and transformer ratings without changing the hardware. Short-circuit pickup Ii is settable from 1.5 to 9 times In (630 A), which gives you flexibility to ride through motor inrush or transformer magnetizing current while still clearing a bolted fault fast. The LI curve means no short-time delay stage — if you need selective coordination with downstream breakers, the 3VA2 family offers ETU350 or ETU600 variants with ST delay. ## Integrated accessories — shunt trip and aux switches Factory-fitted with a shunt trip rated 208-277 V AC 50/60 Hz on the left side and two auxiliary switches (HP type). The two aux switches provide independent status feedback — one for the open/closed position, the other can be wired into a separate control circuit or SCADA input. The 4-pole 630 A frame occupies roughly 280 mm width on the rail — plan your enclosure fill factor accordingly. The shunt trip terminals are on the left side; aux switches on the right. Wire the shunt trip coil from a separate control transformer or UPS if you need guaranteed trip under voltage sag conditions.","metaTitle":"Siemens 3VA2463-6HL42-0KB0 Circuit Breaker, 630A, 85kA @ 415","metaDescription":"Siemens 3VA2 IEC frame 630, breaking capacity class H, Icu=85kA @ 415V AC.
