What this MCCB carries and where it fits
The Siemens SENTRON 3VA2325-7MN32-0HC0 is a 3-pole molded case circuit breaker rated for 250 A continuously across the full 40 °C to 70 °C ambient range — no derating curve to calculate, which simplifies panel thermal budgeting. Breaking capacity hits 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 7.5 kA at 690 V — numbers that put it squarely in the high-fault category for industrial main feeders or large motor branch circuits. Designed for motor protection, it ships with a shunt trip release (STL) and two HQ auxiliary switches — meaning it can be remotely tripped and its status wired back to a PLC or annunciator without adding external relays.
Panel fit and integration
Dimensions are 110 mm deep, 138 mm wide, 248 mm tall — a standard SENTRON 3VA2 frame footprint that drops into existing 3-pole MCCB cutouts and busbar arrangements without re-drilling gland plates. The basic switch variant is 3VA2325-7MN32-0AA0; this -0HC0 suffix adds the shunt trip and HQ aux switches, so if your BOM calls for the bare breaker plus separate trip coil, the -0AA0 is the base, but this -0HC0 saves panel wiring labor.
