The Schneider Electric EAV67703 is a 2-pole Residual Current Device (RCD) from the Acti9 series. This device, also known as a ground fault circuit interrupter, is designed to protect against electric shock and fire hazards by automatically disconnecting a circuit when it detects a dangerous leakage current to earth. This model is a Type AC RCD suitable for detecting alternating sinusoidal residual currents, commonly used in residential and commercial electrical installations.
