Its 800 V rated insulation voltage and breaking capacities ranging from 440 kA at 240 V down to 52.5 kA at 690 V (–) mean it handles high-fault-current service entrance or main feeder duty where upstream transformer capacity is substantial.
Communication and monitoring built in
This MCCB carries a communication function and an other measurement function, meaning it can report load current, power, and status over a bus — useful for a BMS or SCADA system watching the main feed. The ground-fault monitoring version uses summation current formation on L + N conductor, so it detects leakage without a separate GFCI module.
No undervoltage release or trip indicator on this variant, so if remote shunt-trip or local status indication is needed, step to a different order code in the 3VA family.
