Residual current device ETI EFI6-P2 2P 80A 0.03A type AC 6kA (2061254)

ETI EFI6-P2 is a residual current device designed to protect people and electrical circuits from leakage currents and to improve the safety of electrical installations in residential, commercial, and similar facilities. It belongs to the differential relay category and is intended for use in single-phase circuits with a neutral conductor, as indicated by the 1+N configuration. This makes it suitable for group lighting circuits, socket circuits, and other lines where residual current monitoring is required. The device is rated for a current of 80 A and a residual operating current of 0.03 A. Such sensitivity allows the device to respond to small leakage currents that may appear due to insulation damage or contact with live parts. The AC type is intended for circuits with sinusoidal alternating current. Since the device has no time delay, it disconnects the circuit immediately in an emergency situation, which is important for fast fault isolation. The rated AC voltage is 230/240 V, and the rated frequency is 50/60 Hz, so the device can be used in standard low-voltage networks. The nominal short-circuit current Inc is 6 kA, which corresponds to common protection requirements in distribution boards. The device is mounted on a TH 35 DIN rail, which simplifies installation in modular panels together with other modular devices. The housing depth is 68 mm and should be considered when planning the layout inside the enclosure. The permissible conductor cross-section is 1 to 25 mm², providing compatibility with widely used cable and conductor lines. The IP20 degree of protection indicates basic protection against contact with hazardous parts, so installation and operation are intended inside an electrical distribution board. The device complies with IEC/EN 61008, the standard governing residual current devices without built-in overcurrent protection.
