40 A MCCB with flat thermal derating to 70 °C
That flat thermal performance is the spec that matters when you're stacking breakers in a packed cabinet. Interrupting capacity reaches 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — headroom for high-fault installations where a standard MCCB would weld closed.
Footprint and integration
Power loss is 1.2 W maximum.
Built-in communication and ground-fault monitoring
The ground-fault monitoring uses summation current formation on L + N conductors, detecting leakage without an external GFCI relay. Trip indicator is not fitted, so fault events are signaled through the communication channel rather than a local flag.
