The frame is 140 mm wide, 158 mm tall, 70 mm deep — standard panel-mount footprint for a 250 A MCCB, no special cutout needed.
Interrupting ratings and thermal derating
The interrupting curve drops from 187 kA at 240 V to 121 kA at 415 V, then 36 kA at 440 V, and 17 kA at 690 V — that 690 V figure tells you this breaker can serve 690 V line-to-line systems, rare for a 250 A frame. Thermal derating starts at 55 °C: still 250 A at 50 °C, then 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C.
Auxiliary contacts and trip indication
That lets the PLC or annunciator distinguish a maintenance disconnect from a real event.
