The Siemens SENTRON 3VA2325-6HN32-0BH0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C through 70 °C — no derating needed across that band, which simplifies panel sizing in warm enclosures. Breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V.
That depth is the key number for shallow enclosures — confirm the back-can clearance before wiring. An undervoltage release (UVR) is fitted, so verify control voltage matches the coil rating before applying power. A mechanical trip indicator is present — no voltage trigger or communication function on this variant. Ground-fault monitoring is not integrated.
