The Siemens 3VA2563-5MN32-0HL0 is a 3-pole IEC frame 1000 molded-case circuit breaker rated for motor protection, carrying a 55 kA Icu at 415 V AC — breaking capacity class M. The ETU350M electronic trip unit provides LSI protection: long-time (Ir) adjustable from 250 A to 630 A for overload, short-time (Isd) from 3 to 15 times Ir for selective coordination downstream, and instantaneous (Ii) fixed at 15 × In (630 A) for hard short-circuits. This is sized for a motor load up to roughly 315 kW at 400 V (assuming 2× FLA headroom), or a feeder feeding a group of motors with a common bus.
Integrated accessories — shunt trip and auxiliary switch complement
All accessories are internal to the breaker housing, so no external wiring modules are needed.
