What this 250A MCCB does for a panel
At 415 V and 440 V it still holds 242 kA, and at 500 V it's 187 kA, so it handles most low-voltage plant distributions.
Above that it derates linearly — 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. That matters if the panel sits near a furnace or in a hot mezzanine. Maximum power loss is 50.5 W, which you'll need to account for in the enclosure thermal budget.
Built-in auxiliary switches and undervoltage release
That means you get status feedback for remote monitoring — the aux switches signal open/closed, the trip alarm flags a fault trip, and the UVR drops the breaker if control voltage falls below a threshold. No communication function built in, so it's a standalone protection device, not a networked power meter.
The basic switch assembly carries order code 3VA2225-7HN32-0AA0, so if you're replacing just the switching mechanism you can order that subassembly.
