Siemens 3VA2450-5MP32-0AE0 is a 3-pole IEC motor protection circuit breaker on the 3VA2 Frame 630 platform. Rated In=500A with an ETU550M LSI trip unit — overload adjustable 200-500A, short-circuit pickup Isd=1.2-15x In and instantaneous Ii=3-15x In. Breaking capacity class M gives you Icu=55kA @ 415V, so it clears a bolted fault up to that level without blowing upstream. Busbar connection and four auxiliary switch changeovers are built in.
