That 630 A figure is the Iu — the uninterrupted current it carries in open air at 40 °C ambient; if your panel runs hotter, the thermal derating curve drops it to 520 A at 70 °C, so the real-world ampacity depends on enclosure conditions. The breaking capacity hits 330 kA at 240 V and still holds 242 kA at 415/440 V, which puts it in the high-interrupting class for large distribution or industrial main feeders where fault currents are severe. The ETU350 release provides adjustable long-time, short-time, instantaneous, and ground-fault protection curves — it is a fully electronic trip, not a thermal-magnetic, so coordination studies and selective tripping are practical downstream. ## Panel integration — footprint and wiring The breaker measures 110 mm deep by 138 mm wide by 248 mm tall. The 110 mm depth matters for shallow enclosures; verify gland-plate clearance before committing the back panel. Latching endurance is rated at 15 000 cycles — that is the mechanical life for the switching mechanism, not the electrical endurance under load. For frequent switching applications (like capacitor bank or welding control), check the electrical endurance curve in the full datasheet against your duty cycle. ## What the auxiliary contacts and releases add The HQ designation means high-quantity or high-reliability contact blocks — they are rated for the breaker's auxiliary circuit and provide status to a control system. The shunt trip allows a remote pushbutton, PLC output, or safety relay to open the breaker without a manual handle operation. There is no undervoltage release on this variant, and no communication module or phase-failure detection built in.","metaTitle":"Siemens 3VA2463-7HN32-0HC0 SENTRON MCCB, 630 A, 330 kA","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0HC0 molded case circuit breaker, 630 A rated current, 330 kA at 240 V breaking capacity, ETU350 release, shunt trip, current lifecycle stage.
