Breaking capacity across voltage levels
Rated ultimate short-circuit breaking capacity (Icu) is 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. These figures place it in the high-interrupting category — suitable for installation close to large transformers or on high-fault-current busbars where standard 25–65 kA MCCBs would require series-rated coordination.
Dimensions: 181 mm height, 105 mm width, 86 mm depth. An optional motor drive (listed as a product extension) allows remote open/close for automated transfer schemes.
