What this 630 A MCCB does on the line
Communication function is built in, meaning it can talk to a higher-level system for monitoring or remote trip without an external module. No ground-fault monitoring version is fitted here (that's a separate variant), so if you need GF protection, this isn't the one.
The continuous current rating of 630 A is at 40 °C ambient inside the enclosure. Out here in the grease, if your panel runs hotter — say 50 °C — you derate to 570 A; at 60 °C it drops to 510 A; at 70 °C you're down to 450 A. That derating curve is the one that decides whether this breaker carries your full load on a hot summer day. The dimensions are 248 mm tall, 138 mm wide, and 110 mm deep — a 3-pole frame that fits standard MCCB mounting patterns in a distribution section. Panel builders need to account for the 164.5 W maximum power loss when sizing ventilation or forced-air cooling inside the enclosure.
