The Siemens 3VA2325-6HL32-0HL0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. With a 242 kA interrupting capacity at 240 V, it handles high-fault scenarios typical of industrial distribution without cascading upstream. The 3-pole line-protection design includes a shunt trip release (STL) and a complement of two auxiliary switches plus one trip alarm and one electrical alarm switch (HQ configuration).
Interrupting capacity and selectivity
The interrupting ratings step down with system voltage: 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 690 V figure is the one to watch — if your line side feeds a 690 V bus, the available fault current must stay under 7.5 kA or you need a current-limiting upstream device. The minimum trip threshold is 375 A, and the maximum setting goes to 3 000 A, giving a wide coordination band for downstream feeders.
Panel fit and auxiliary wiring
The MCCB measures 138 mm wide by 248 mm tall by 110 mm deep — standard footprint for this SENTRON frame size. The auxiliary switch block (2 aux + 1 trip alarm + 1 electrical alarm) and the integrated shunt trip release occupy the accessory slots; no communication module is fitted, so this is a hardwired-only breaker. The undervoltage release is absent on this variant, so the shunt trip is the sole remote-trip path. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
