It carries a 10 kA breaking capacity per IEC/EN 60898-1 and IEC 60947-2, which means it can safely interrupt fault currents up to 10 kA at 400 V AC without welding or arcing over — enough for most commercial and light industrial installations where the prospective short-circuit current is within that range. The auxiliary switch (1NO+1NC) integrated into the housing lets the PLC or SCADA system monitor the breaker state without adding an external contact block, saving one DIN slot.
Panel fit and environmental range
Ambient temperature range from -40 °C to 75 °C covers freezer lines and hot machine cabinets, though above 55 °C the humidity derating curve applies (95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C).
