The 4-pole construction with adjustable N-conductor protection (OFF, 50%, 100%) makes it suitable for 3-phase + neutral systems where you need to protect the neutral against harmonics or unbalanced loads. The ETU350 LSI trip unit provides adjustable long-time (Ir=250A...630A), short-time (Isd=1.5...9x Ir), and instantaneous (Ii=9x In) protection. The LSI designation means it has short-time delay for selectivity coordination downstream — you can set the Isd delay to ride through inrush without nuisance tripping, then clear a bolted fault fast. The shunt trip left (208-277 V AC 50/60 Hz, 220-250 V DC) and auxiliary switch are factory-installed accessories, so this breaker arrives ready for remote tripping and status feedback without field retrofitting. ## Deployment context The 630 A frame size and 110 kA interrupting rating place it in main or feeder breaker duty for industrial switchboards, not branch-circuit protection. The shunt trip and auxiliary switch give the controls integrator a clean way to interface with a PLC or safety relay for emergency-off or status monitoring without adding external contactors.","metaTitle":"Siemens 3VA2463-7HN42-0KF0 Circuit Breaker, 630A, 110kA @ 41","metaDescription":"Siemens 3VA2463-7HN42-0KF0 IEC frame 630 circuit breaker, breaking capacity class C, Icu=110kA @ 415V, 4-pole, ETU350 LSI, In=630A.
