It carries an ETU345 LI electronic trip unit configured for line protection — the LI curve means long-time and instantaneous protection, no short-time delay. Rated continuous current In is 630 A, but the overload protection (Ir) is adjustable from 252 A to 630 A, and the instantaneous pickup Ii is fixed at 9 × In (5670 A). This is a busbar-connected unit, so it lands directly on a panel bus, not a line-side cable. The ETU345 LI trip unit is electronic, so it offers better accuracy and adjustability than a thermal-magnetic breaker; the Ir adjustment range (252–630 A) lets you match the breaker to the actual load without changing the frame. The lack of overload protection (the description flags 'without overload protection') means this unit is intended for use where the overload function is handled elsewhere — typically a separate overload relay for motor circuits, or a downstream feeder breaker. The instantaneous pickup at 9 × In is a fixed value, so coordination studies should account for that threshold. ## Deployment Context This breaker mounts in a switchboard or panel via the busbar connection — no DIN-rail adapter, it bolts directly to the bus. The 3VA2 frame is the 630 A frame size; panel cutouts and bus spacing follow the standard 3VA2 footprint. For an OEM panel builder, the busbar connection saves wiring time on the main feed, but verify the busbar center-to-center spacing matches your panel layout.","metaTitle":"Siemens 3VA2463-5HR32-0AA0 Circuit Breaker, 630A, 55kA @ 415","metaDescription":"Siemens 3VA2463-5HR32-0AA0 IEC frame 630 circuit breaker, 55kA breaking capacity at 415V, ETU345 LI trip unit, 630A rated current.
