The Siemens 3VA2225-6JP32-0BE0 is a 3-pole IEC frame 250 molded-case circuit breaker in breaking capacity class H, rated Icu=85kA at 415 V AC. It carries an ETU550 electronic trip unit with LSI protection — overload (Ir) adjustable 100 A to 250 A, short-time (Isd) 0.6 to 10× In, and instantaneous (Ii) 1.5 to 10× In. The build includes an undervoltage release (24 V DC) and four HQ auxiliary switches. N-conductor protection is available as an option via an external current transformer.
The ETU550's LSI curve gives selective coordination downstream: you can set Isd delay to ride through motor inrush while still clearing a bolted fault. The 24 V DC undervoltage release is common for safety circuits that drop out on loss of control voltage; verify polarity and that the coil draw fits your 24 V DC supply budget.
