Breaking capacity runs 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V — so at typical 480 V distribution levels it clears faults well above most service-entrance requirements. The trip unit is adjustable between 375 A and 2 500 A, meaning this breaker can be set to protect a feeder or a large motor circuit within that window. Thermal derating is published: full 250 A up to 50 °C, then 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C.
No communication module on board, so it's a straight power path with auxiliary contacts for status feedback.
