Residual current device ETI EFI6-P2 2P 16A 0.03A type AC 6kA (2061250)

This residual current device from ETI is intended for protection of electrical circuits against leakage currents and indirect contact. It is used in residential, administrative, and commercial installations where automatic disconnection is required when a dangerous residual current appears. The device is suitable for single-phase circuits thanks to its 1+N pole configuration, and it is designed for installation on a TH 35 DIN rail, which simplifies integration into distribution boards with other modular devices. The model is rated for a current of 16 A and a residual current sensitivity of 0.03 A, or 30 mA. This makes it appropriate for group circuits such as lighting, socket outlets, and the connection of household loads. The AC type indicates response to alternating residual current. The breaking capacity of 6 kA supports operation in networks with the corresponding short-circuit current level. Since the device has no intentional delay, it disconnects the affected circuit immediately after detecting a fault, helping limit the development of hazardous conditions. Electrical characteristics include an AC rated voltage of 230/240 V and a rated frequency of 50/60 Hz, so the device can be used in standard low-voltage power systems. The permitted conductor cross-section ranges from 1 to 25 mm², which gives flexibility when selecting installation conductors for typical wiring layouts. The housing depth is 68 mm, an important parameter when planning space inside the enclosure and arranging incoming conductors. The device complies with IEC/EN 61008 and has an IP20 degree of protection, which confirms its intended use inside electrical enclosures. ETI EFI6-P2 combines residual current monitoring, fast disconnection, and modular mounting in a format suitable for common electrical distribution systems and circuit protection tasks.
