The 10 A rated operational current and C-curve tripping characteristic mean it protects final circuits with moderate inrush, like lighting or small motor loads, while the 30 mA rated residual fault current provides additional protection against electric shock. The Type A designation means it detects both sinusoidal AC residual currents and pulsed DC residual currents — important for circuits with rectifiers or switching power supplies. The higher IEC figure applies when the RCBO is used in industrial distribution where the prospective short-circuit current may exceed the domestic standard. The 1P+N configuration switches the line conductor and disconnects the neutral, which is standard for single-phase final circuits in TN or TT systems.
Halogen-free and silicon-free construction. The neutral conductor is switched, and touch protection is provided.
