MCCB for line protection with ETU320 and shunt trip
Breaking capacity runs 187 kA at 240 V AC, 121 kA at 415 V AC, and 3.75 kA at 690 V AC — the 690 V figure is the one to watch if you're protecting a 690 V motor feeder; at that voltage the interrupting rating drops sharply, so verify the available fault current at the panel.
Front IP40 keeps out tools and fingers but not washdown; keep it behind a sealed door in wet environments.
