The Siemens SENTRON 3VA2225-5HL32-0JH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current (Iu) at 40 °C, with the same rating holding flat through 50 °C — useful when the panel ambient runs warm but not hot. Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V. At 690 V the 5.1 kA rating is modest; if your system runs 690 V with fault currents above that, this breaker is not the right choice for that voltage leg. The overcurrent release is an ETU320 — a basic electronic trip unit with fixed settings (no adjustable long-time, short-time, or ground-fault pickups). It is a line-protection breaker, not a motor-protection or feeder-selectivity device. There is no communication function, no phase-failure detection, and no undervoltage release fitted.
No DIN-rail clip on this frame; it is screw-fixed.
