The Siemens SENTRON 3VA2463-5JP32-0HH0 is a 3-pole molded case circuit breaker rated for line protection at 630 A continuous (Iu) at 40 °C, with an insulation voltage of 800 V. Breaking capacity hits 187 kA at 240 V, 121 kA at 415 V, and still holds 75.6 kA at 500 V — that's enough SCCR to sit upstream of most motor control centers without needing a current-limiting fuse ahead of it. The shunt trip (STL) release is built in, and the auxiliary contact block provides 2 aux switches plus 1 dedicated trip-alarm switch (HQ type) — so you get both a status feedback and a separate fault-signal contact without adding an external module. Max power loss runs 162 W at rated load, which drives ventilation planning if the breaker is enclosed in a low-profile panel.
Current production — no end-of-life watch needed
This order code carries a current lifecycle status from Siemens. No phase-out notice, no last-time-buy deadline to track.
Mounting and integration into a 3-pole MCCB footprint
It's a standard SENTRON 3VA2 frame size, so the mounting hole pattern and bus-bar connection centers match the rest of the 3VA2 family. No rewiring if you're swapping from another 3VA2 frame breaker of the same pole count; the line and load lugs land in the same positions.
Derating and operating range — plan for the ambient
At 50 °C it carries 570 A, at 60 °C it's 510 A, and at 70 °C it's 450 A — so if your panel ambient runs hot, size the breaker for the derated current, not the nameplate.
