Its 187 kA interrupting capacity at 240 V AC handles high-fault scenarios typical in industrial feeder circuits, while the 121 kA rating at 415 V and 440 V covers common European and North American distribution voltages. This MCCB carries a communication function, meaning it can integrate with plant monitoring or energy management systems — useful for a pulp mill or continuous process line where you want breaker status and load data back in the DCS without a separate I/O run.
At 500 V it's 75.6 kA, and at 690 V it drops to 3.7 kA.
Thermal performance across the panel ambient range
That's a solid spec for a mill MCC room or a hot rooftop panel where summer ambients push 55 °C. Power loss is 10 W maximum, so heat buildup inside a compact panel is manageable.
Physical fit and auxiliary configuration
The breaker ships with three auxiliary switches (HQ type) fitted, so you get remote status indication without ordering add-on modules separately.
