The Siemens 3VA1063-2ED32-0AA0-ZD00 is a 3-pole IEC frame 100 molded case circuit breaker rated 63 A continuous, with a breaking capacity of 16 kA at 415 V (class B). It ships with a TM210 thermal-magnetic trip unit: the thermal overload is fixed at Ir=63 A (no adjustment range), and the magnetic short-circuit pickup is fixed at Ii=10 x In, so it trips instantaneously at 630 A. That fixed-trip configuration is common for dedicated motor or feeder circuits where you want a predictable, non-adjustable protection curve. The suffix ZD00 indicates a nut keeper kit included for DC Power OEM applications in China — a panel-mounting accessory that keeps the bus-bar nuts captive during assembly. If you're integrating this into a Chinese OEM panel, that kit saves a step; if you're buying for a standard DIN-rail enclosure elsewhere, it's just extra hardware in the box.
Because the 3VA1 series is a current catalog line, lead times are generally consistent with Siemens' standard molded-case breaker production cycle — no special sourcing or broker channel needed.
