The Siemens 3VA1463-5EF42-0AA0-ZD00 is a 4-pole IEC frame 630 circuit breaker from the 3VA1 series, rated for line protection with a TM240 ATAM trip unit. Its headline breaking capacity is Icu=55kA at 415V (class M), meaning it can safely interrupt fault currents up to that level without upstream cascading — sized for high-fault industrial distribution panels where the available short-circuit current is substantial. Overload protection is adjustable via Ir from 440 A to 630 A (the In rating), and short-circuit protection Ii is set at 4 to 8 times In. The N conductor is unprotected, and the breaker includes a nut keeper kit for DC Power OEM applications in China.
