The Siemens 3VA2563-5MN32-0CH0 is a 3-pole IEC frame 1000 motor protection circuit breaker rated In=630A with a breaking capacity Icu=55kA at 415V AC. That Icu figure places it in breaking capacity class M — it can safely interrupt a 55kA fault current at 415V without upstream cascading, which is the threshold you need for high-fault industrial distribution panels. The ETU350M trip unit gives you LSI protection: long-time (overload) adjustable from 250A to 630A, short-time (short-circuit) from 3 to 15 times Ir, and instantaneous fixed at 15 times In. That adjustability lets you coordinate with downstream breakers and motor starters without swapping trip units.
Integration notes
The UVR drops the breaker on loss of control voltage — common for emergency-stop chains or undervoltage protection schemes.
