This one does. That means if your control voltage drops out, the breaker opens without waiting for a fault. Handy for coordinated start/stop sequences or safety interlocks where you want the motor off when the control power goes away. ## Breaking capacity — the real-world fault current it can handle Breaking capacity is where this breaker earns its keep in heavy industrial panels. At 240 V it's rated 187 kA; at 415 V and 440 V it holds at 121 kA; at 500 V it's 75.6 kA; and at 690 V it's still 17 kA. The 690 V rating at 17 kA also tells you it's usable on 600 V class systems common in North American mining and oilfield installations. ## Thermal derating — how hot can your panel get? Above that it starts to step down: 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C. That's a shallow derating curve — you lose only 25 A over a 20 °C rise from 50 to 70 °C. So if your panel runs warm because it's packed tight or sitting next to a hot process line, this breaker still carries most of its rated current. Plan your ventilation or enclosure sizing accordingly. It mounts via the breaker's own base — no DIN rail adapter needed for this class of breaker; it bolts directly into the panel or onto a mounting plate. The 138 mm width means it occupies three 45 mm pole spaces if you're laying out a multi-breaker lineup. ## What it doesn't have — and why that matters for your BOM If your application requires any of those, you'd need a different variant in the 3VA2 family or an add-on module. The trip indicator is also absent, so there's no local mechanical flag showing whether the breaker tripped on overload or was manually opened. That's typical for the base motor-protection configuration — the ETU350M handles the protection logic, and you get the status from the undervoltage release circuit.","metaTitle":"Siemens 3VA2325-5MN32-0CA0 SENTRON MCCB, 250 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2325-5MN32-0CA0 SENTRON molded case circuit breaker, 250 A rated, 3-pole motor protection with ETU350M release and undervoltage trip.
