Residual current device ETI EFI6-P2 2P 63A 0.03A type AC 6kA (2061253)

ETI EFI6-P2 is a residual current device designed to monitor leakage currents and disconnect the supply when a dangerous difference between current in the phase and neutral conductors appears. In practice, it is used in residential, commercial, and other low-voltage installations where additional protection against electric shock is required, as well as to reduce the risk of damage caused by current leakage to earth. This model has a 1+N pole configuration, meaning one protected pole and one neutral conductor. The rated current is 63 A, which makes the device suitable for protecting group circuits and separate loads with higher current demand. The residual operating current is 0.03 A, or 30 mA, a common sensitivity level for personal protection. Type AC means the device responds to sinusoidal alternating residual currents. The breaking capacity for short-circuit conditions is 6 kA, which is an important parameter for operation in networks where fault currents of this level may occur. The device operates without delay, so it trips immediately after detecting a leakage current. The rated AC voltage is 230/240 V at 50/60 Hz, which allows use in standard single-phase power systems. Mounting is carried out on a TH 35 DIN rail, making installation in distribution boards straightforward and compatible with other modular devices. The body depth is 68 mm, and the terminal design supports conductor cross-sections from 1 to 25 mm². The IP20 degree of protection indicates that the device is intended for installation inside electrical cabinets, where basic protection against accidental contact with live parts is provided. Compliance with IEC/EN 61008 confirms that this is a residual current device meeting the requirements of the relevant standard. Overall, EFI6-P2 is a modular protective device for switching off circuits when leakage current is detected and for improving electrical safety in low-voltage networks.
