It's designed for line protection in distribution panels, with an interrupting capacity that reaches 330 kA at 240 V AC and holds 242 kA at 415 V and 440 V, then steps down to 187 kA at 500 V and 4.5 kA at 690 V.
Continuous current holds at 250 A from 40 °C 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. Size the load at the actual ambient, not the 40 °C sticker. Power loss is 50.5 W maximum at rated load. That's heat that stays inside the enclosure; factor it into the panel thermal budget if you're stacking several breakers in a confined space.
Auxiliaries and communication
The trip indicator is present, and a communication function is built in — that means it can report status or trip events to a monitoring system without an external module. The basic switch variant is 3VA2225-7KP32-0AA0, so if you need a bare breaker without auxiliaries, that's the base order code.
Dimensions: 86 mm depth, 105 mm width, 181 mm height. No IP rating is listed on this record, so it's intended for enclosed panel mounting, not washdown or outdoor exposure.
