This is the variant with two auxiliary switches HP fitted, no undervoltage release, and no communication module — a straight feeder or distribution breaker for a 250 A bus.
Interrupting ratings and selectivity headroom
The interrupting capacity is what sets this frame apart: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. For a 250 A MCCB, those numbers mean it can sit upstream of a large transformer or feed a high-fault industrial bus without cascading into the main breaker.
Above that, derate linearly: 240 A at 55 °C, 235 A at 60 °C, 230 A at 65 °C, and 225 A at 70 °C.
Dimensions: 248 mm height, 138 mm width, 110 mm depth.
