The Siemens SENTRON 3VA2325-5HN32-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity hits 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V, so it handles high-fault utility feeds and transformer secondaries without cascading upstream. The 110 mm depth, 138 mm width, and 248 mm height fit standard SENTRON panel cutouts.
At 415 V (common IEC industrial voltage) the 121 kA rating still clears most distribution transformer secondary faults. The 7.5 kA at 690 V is the tail — adequate for 690 V drives or motor control centers, but not for high-fault 690 V utility ties. For a panel originally specified around the 3VA2225-5HN42-0BB0, the 3VA2325-5HN32-0AB0 shares the same SENTRON 3VA frame footprint and mounting pattern, so it drops in without rewiring — verify the lug kit matches your cable size.
Environmental and installation
The 3-pole design with no trip indicator and no voltage trigger means it's a straight thermal-magnetic or electronic-trip MCCB (trip unit type not specified in this listing). Mounts in the standard SENTRON 3VA panel footprint; the 138 mm width matches the 3VA frame width for multi-pole grouping.
