The Siemens 3VA1463-6EF42-0AA0-ZD00 is a 4-pole IEC frame 630 circuit breaker with class H breaking capacity — Icu rated 70 kA at 415 V. The thermal-magnetic TM240 trip unit gives overload protection adjustable from 440 A to 630 A (Ir) and short-circuit pickup (Ii) from 4 to 8 times In.
Deployment Context
The 630 A frame size and 4-pole footprint mean it occupies a full-width panel position — plan for adequate heat dissipation and cable bending radius around the terminals. The nut keeper kit is a small but useful detail for OEMs building DC Power cabinets in China: it keeps the mounting hardware captive during assembly, reducing dropped-fastener delays on the line.
