The Siemens 3VA2563-5MN32-0KL0 is a current-production IEC frame 1000 molded-case circuit breaker, 3-pole, rated 630 A continuous, with a breaking capacity of Icu=55 kA at 415 V AC — class M on the 3VA2 platform. The trip unit is an ETU350M with LSI protection: long-time (overload) pickup Ir adjustable from 250 A to 630 A, short-time (short-circuit) pickup Isd from 3 to 15 × Ir, and instantaneous pickup Ii fixed at 15 × In. That spread lets you coordinate selectivity downstream — set Ir near the motor FLA, Isd above the inrush spike, and Ii as a hard fault backup. The shunt trip (STL) coil operates on 220–250 V DC or 208–277 V AC, so it fits common control voltages across regions.
Accessories and auxiliary contacts
The auxiliary switches report breaker position to a PLC or status lamp; the trip alarm and electrical alarm switches distinguish a fault trip from a manual open — useful for remote diagnostics on a motor control center (MCC) bucket.
