Line protection MCCB with high interrupting capacity
The 4-pole design handles three-phase plus neutral, and the interrupting capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — figures that suit high-fault industrial distribution where upstream transformer capacity or parallel sources drive available fault current above typical MCCB ratings.
Full 16 A rating holds from 40 °C up to 55 °C ambient; at 60 °C it derates to 15 A, and at 70 °C it holds at 15 A. The enclosure front carries IP40 protection — suitable for dry indoor panel environments where tools or fingers are the main concern, not washdown. Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth, fitting standard MCCB mounting footprints.
