The 630 A frame covers feeder and large motor circuits; the ETU550 allows adjustable overload protection Ir from 250 A to 630 A and short-circuit pickup Isd from 0.6 to 9x In, so it fits a range of downstream loads without changing the breaker frame. For most industrial 400 V distribution, this covers high-capacity transformer secondaries and large motor control centers where fault levels run 50 kA or higher. The built-in shunt trip (left side, 208-277 V AC 50/60 Hz, 220-250 V DC) allows remote emergency-off or undervoltage release without an external shunt trip module. ## Panel Integration Mounts in a standard IEC 60947-2 compliant panel — DIN-rail or screw-mount depending on the 3VA2 base plate. The 4-pole form factor (3 phases + neutral) with adjustable N-conductor protection (OFF to 100%) suits 3-phase 4-wire systems where the neutral must be protected or left unprotected. The nut keeper kit (included) prevents terminal hardware from loosening under vibration in transport or high-fault installations. Verify the shunt trip coil voltage matches the control circuit before wiring; the left-side shunt trip occupies the accessory slot closest to the line terminals.","metaTitle":"Siemens 3VA2463-5JP42-0KB0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5JP42-0KB0 IEC frame 630 circuit breaker, breaking capacity class M, Icu=55kA @ 415V, ETU550 LSI protection, 630A.
