Residual current device ETI EFI6-P2 2P 25A 30 mA type AC 6kA (2061251)

ETI EFI6-P2 is a residual current device designed to disconnect electrical circuits when leakage current appears, helping protect people and equipment in residential and commercial installations. It is used in distribution boards where prompt switching off is required if an unsafe differential current occurs. The device is suitable for lighting circuits, socket groups, and individual loads that need residual current protection in standard low-voltage networks. This model has a 1+N pole configuration, a rated current of 25 A, and a residual current sensitivity of 30 mA. Such parameters make it appropriate for branch-circuit protection in everyday electrical systems. The AC type indicates operation with alternating differential current, which is typical for conventional AC networks. The device operates at 230/240 V AC and 50/60 Hz, so it fits common mains conditions used in many installations. The breaking capacity Inc is 6 kA, which is an important characteristic for applications where the installation must withstand short-circuit-related stress within the specified limits. Tripping occurs without delay, allowing immediate response to a fault condition. The permitted conductor cross-section is 1 to 25 mm², which supports a wide range of wiring options during panel assembly and connection work. Mounting is carried out on a TH 35 DIN rail, making the device compatible with standard modular enclosures and simplifying installation in switchboards. The housing depth is 68 mm, an important detail when planning the layout of the panel and available installation space. With an IP20 degree of protection, the unit is intended for indoor installation inside electrical cabinets and enclosures, where direct contact with live parts is prevented by the enclosure structure. The device complies with IEC/EN 61008, confirming its classification as a residual current device according to the relevant standard. ETI EFI6-P2 combines a 1+N pole layout, 25 A rated current, 30 mA sensitivity, type AC operation, and 6 kA short-circuit withstand capability, making it a practical solution for residual current protection in modular electrical systems.
