RCBO with Type A residual current and C characteristic
It carries a 25 A rated current at 30 °C ambient and trips on residual fault currents of 30 mA, Type A — meaning it detects sinusoidal AC faults and pulsating DC fault currents up to 6 mA ripple, per IEC 60755.
The thermal derating curve is published: 24 A at 40 °C, 23.5 A at 45 °C, 23 A at 50 °C, 22.5 A at 55 °C, and 22 A at 60 °C (–).
