It is a 1P+N unit rated at 40 A with 300 mA sensitivity, Type AC, meaning it detects sinusoidal AC residual currents only — suitable for general-purpose socket-outlet and lighting circuits where no electronic loads with DC ripple are present. Rated operational voltage is 230 V AC phase-to-neutral at 50 Hz, with an insulation voltage of 400 V AC and impulse withstand of 6 kV per EN 61009-1. The device is voltage-independent — it trips on residual current alone, no external supply needed.
Certified to IEC 60947-2, EN 61009-1, and EN 61009-2-1. Operating temperature range -5 to 60 °C, storage -40 to 60 °C, with 95% relative humidity at 55 °C. Maximum operating altitude 2000 m.
