What the ratings mean for your panel
The 3VA2463-5JP42-0LD0 is a SENTRON 3VA2 molded case circuit breaker on the IEC frame 630 platform, rated 630 A continuous with an ETU550 electronic trip unit providing LSI protection — long-time, short-time, and instantaneous. The 55 kA interrupting capacity at 415 V AC (breaking capacity class M) means it can safely clear faults up to that level without upstream fuses or a bigger frame; that's the figure that governs your selectivity study, not the continuous current. The ETU550 gives you adjustable overload protection from 250 A up to 630 A, short-time pickup from 0.6 to 9x In, and instantaneous pickup from 1.5 to 9x In, plus adjustable N-conductor protection (OFF, up to 100%). That's a lot of coordination range in one package — useful when you're feeding a mix of motor loads and distribution downstream.
Deployment context
This 4-pole breaker lands in a switchboard or distribution panel — it's a front-terminal connection with nut keeper kits on both sides, so you're wiring lugs or bus bars, not plugging into a base. The IP40 front face keeps finger-safe protection inside the enclosure; it's not rated for washdown or outdoor exposure without a secondary cabinet. At 630 A frame size, you're looking at copper bus work or large cable terminations — plan your bending radius and torque specs accordingly.
How it sits against the 3VA2116-5HL32-0AK0
The closest sibling in the ledger is the 3VA2116-5HL32-0AK0 — a 3-pole, 160 A frame with an ETU320 LI trip (no short-time protection) and a lower 25.5 W power loss versus this 630 A unit's higher dissipation. The frame 630 here is physically larger (wider at 140 mm vs 105 mm for the 3-pole 160 A frame) and the 4-pole footprint means a different bus arrangement. If your panel was laid out for the smaller 3-pole frame, this won't drop in without reworking the mounting and bus connections — the 630 A frame needs its own space and lug kit.
