What this 3VA1 breaker packs
The Siemens 3VA1063-3ED32-0LC0 is a 3-pole IEC frame 100 circuit breaker rated 63 A with TM210 thermal-magnetic line protection — fixed overload Ir=63 A, fixed short-circuit protection Ii=10 x In. Breaking capacity is 25 kA Icu at 415 V, class N, which means it clears line-to-line faults up to that level on a 400 V distribution board without needing an upstream current-limiting fuse.
Built-in accessories save panel space
This order code ships with a 24 V DC universal release (shunt trip) and two auxiliary switch changeover contacts factory-fitted — no separate mounting or wiring of add-on modules. The nut keeper kit is also included, which holds the busbar or cable lug nuts captive during installation on a DIN rail or mounting plate.
