The Siemens 3VA1463-6GE42-0AA0-ZD00 is a 3VA1 IEC frame 630 molded case circuit breaker with breaking capacity class H, rated Icu=70kA at 415 VAC. Overload protection Ir is adjustable from 440A to 630A; short-circuit protection Ii is fixed at 8 x In. The N conductor is protected at 100%. This variant includes a nut keeper kit and is specified for DC Power OEM applications in China.
The 630 A frame and adjustable overload (440–630 A) let it serve as a main or feeder breaker in a 400 V distribution panel. The 4-pole configuration with 100% N protection suits systems where the neutral conductor must be switched and protected, common in certain IEC markets.
Deployment Context
Mounts in a standard IEC distribution panel or switchboard. The nut keeper kit simplifies busbar connection during panel assembly. The TM220 thermal-magnetic trip provides time-delayed overload and instantaneous short-circuit response — no external trip unit or power supply needed.
