Its interrupting capacity is what earns it a spot in high-fault installations: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. The breaker includes phase failure detection — if one phase drops out on a motor load, it trips before single-phasing cooks the winding. ## Sizing and environment The 138 mm width is three pole widths at 46 mm per pole — the same footprint as the 3VA1 frame, so a panel laid out for a 3VA1110 will accept this 3VA2325 without re-drilling the mounting plate. It dissipates 37.5 W maximum at full load, which matters for enclosure thermal rise calculations — particularly in a sealed stainless steel panel on a washdown line. For a BOM-critical motor protection MCCB, this is a low-risk line item. If you are holding a spare for a legacy panel, this is the same part number you need — no substitution guesswork.","metaTitle":"Siemens SENTRON 3VA2325-5MN32-0KB0 MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2325-5MN32-0KB0 molded case circuit breaker, 250 A at 40 °C, 3-pole, 187 kA at 240 V.
