What this MCCB delivers
The interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and still 4.5 kA at 690 V. That covers most industrial distribution panels where high fault current is a concern — think large motor control centers or transformer secondaries.
Above that, it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. The IP40 front protection means it's suited for clean indoor environments; no washdown rating here. Maximum power loss is 48 W at rated current. For a densely packed panel, that's a non-trivial heat source — ensure adequate ventilation or forced cooling if you're grouping several of these breakers together.
