It is a 3-pole unit rated for 250 A continuous current across the full ambient range from 40 °C up to 70 °C, meaning it carries the same 250 A without derating in a warm enclosure — a useful simplification for panel builders who want one ampacity number for the entire operating window. The interrupting ratings are substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. Maximum rated current is 3 000 A, and the minimum is also 3 000 A — this is a fixed-rating frame, not an adjustable one. The breaker ships with a 250 A continuous rating, but the frame itself is the 3 000 A platform, which gives mechanical headroom for the high interrupting duty.
The 110 mm depth is a key number for enclosure selection — it tells you the breaker projects 110 mm from the mounting surface, which determines the minimum enclosure depth needed to clear the door or deadfront. The auxiliary switch arrangement is factory-configured as 1 auxiliary + 1 trip alarm, which covers the common signaling needs for a line-side breaker — remote trip indication and breaker status.
