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.
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.
