It's a 3-pole unit with a full-scale rating of 250 A and an adjustable trip range from 50 A minimum to 250 A maximum, so you can dial it in for the actual load without swapping the breaker. Rated current holds at 250 A through 50 °C ambient, then derates to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C — that thermal curve matters if this breaker sits in a hot enclosure or next to other heat sources. Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard 3-pole MCCB footprint for a 250 A frame. That gives you status feedback for PLC or SCADA without adding external relays. Communication function is built in — the breaker can report status and accept remote commands over the bus, which saves wiring on larger switchgear lineups.
