Residual current device ETI EFI-P2 2P 16A/0.03A type AC 10kA (2061210)

ETI EFI-P2 is a residual current device intended for monitoring leakage currents and disconnecting the supply when a dangerous difference between phase and neutral currents appears. It is used in distribution boards of residential, commercial, and household electrical installations where additional protection against electric shock and fault currents is required. The device operates without time delay, which supports fast disconnection of the affected circuit. This model is designed in a 1+N pole configuration and has a rated current of 16 A. The residual operating current is 0.03 A, or 30 mA, which is a common value for personal protection and for detection of leakage currents in the network. Type AC means the device responds to sinusoidal alternating residual currents. It is suitable for single-phase AC systems with a rated voltage of 230/240 V and a rated frequency of 50/60 Hz. The device is mounted on a TH 35 DIN rail, so it can be installed in modular distribution cabinets together with other panel components. The housing depth is 68 mm, which should be considered when planning installation space inside the enclosure. The allowable conductor cross-section range is 1–25 mm², providing flexibility for connection in different wiring schemes while remaining within the specified limits. The rated short-circuit current Inc is 10 kA, indicating suitability for circuits where the prospective fault current may reach this level. The IP20 protection rating means protection against contact with live parts by a finger and confirms that the device is intended for installation inside a closed electrical enclosure. Compliance with IEC/EN 61008 specifies that this is a residual current device without integrated overcurrent protection, used as a dedicated protective element in electrical systems. Overall, the ETI EFI-P2 is a circuit protection device for applications where leakage-current monitoring, rapid disconnection, and standardized modular mounting are required. Its technical parameters make it appropriate for use in fixed installations with typical 230/240 V single-phase supply systems.
