The Siemens 3VA1463-6EF32-0AF0 is a 3-pole IEC frame 630 molded case circuit breaker rated for 630 A continuous current. Its class H breaking capacity delivers 70 kA at 415 V — that means it can safely interrupt a fault up to that level without upstream cascading, sized for high-fault industrial mains. The TM240 ATAM trip unit adjusts overload protection from 440 A to 630 A (Ir) and short-circuit pickup from 4 to 8 times In. Built-in auxiliary switch (changeover H) and a separate trip alarm switch give the panel builder positive status feedback for PLC or remote indication without external relays.
