The interrupting ratings tell the real story: 220 kA at 240 V, 154 kA at 415 V, and still 121 kA at 440 V — numbers that put this in the high-interrupting-capacity class, sized for large transformer secondaries or high-fault industrial distribution panels.
That's a tight thermal curve; most MCCBs start sliding at 50 °C. Power loss maxes at 12 W, which matters for enclosure heat load if you're stacking several breakers.
Panel fit
Dimensions: 130 mm tall, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without surprises. The 70 mm depth means it clears shallow backpanels where some breakers with protruding arc chambers won't. The trip indicator is present, so a quick visual check confirms the breaker has tripped without needing to reset it to find out.
