The Siemens 3VA1463-4GF42-0AA0-ZD00 is a 4-pole IEC frame 630 molded-case circuit breaker with a 36 kA interrupting capacity at 415 V (breaking capacity class S). The thermal-magnetic trip (TM240, ATAM) gives adjustable overload protection (Ir = 440 A to 630 A) and fixed short-circuit protection (Ii = 4 to 8 x In). The 100% N-conductor protection means the neutral pole is fully rated, not just switched — essential for 4-wire systems where neutral loading is continuous. The nut keeper kit included is a small but practical detail for DC Power OEM builds in China — it keeps the terminal nuts captive during wiring, saving time on assembly lines.
