ETI EFI6-P2 Residual Current Device 2P 40A 0.03A Type AC 6kA (2061252)

The ETI EFI6-P2 residual current device is intended for protection of people and electrical circuits against leakage currents, helping reduce the risk of electric shock and insulation damage in low-voltage installations. It is suitable for use in residential, commercial, and general-purpose distribution boards where fast disconnection is required when a differential current appears. This model is a differential relay with a rated current of 40 A and a residual operating current of 0.03 A, which corresponds to 30 mA sensitivity. Such parameters make it appropriate for monitoring leakage in final circuits where personal protection is important. The AC type means the device is designed for alternating-current circuits. The 1+N pole configuration is intended for single-phase networks with a neutral conductor, providing practical use in common household and light commercial systems. The rated AC voltage is 230/240 V, and the operating frequency is 50/60 Hz, so the device is compatible with widely used supply conditions. The short-circuit rated current Inc is 6 kA, which is an important parameter for installations where prospective fault currents must be taken into account. The device operates without time delay, so it disconnects immediately after detecting leakage current, which is relevant for applications that require prompt tripping rather than selective delay. Installation is carried out on a TH 35 DIN rail, which is the standard mounting method for modular equipment in electrical cabinets. The housing depth is 68 mm, making the device suitable for compact assembly layouts in distribution boards. The protection degree IP20 indicates indoor installation inside an enclosure, where direct contact with live parts is not expected. Connection is supported for conductor cross-sections from 1 mm² to 25 mm², allowing use with typical cable sizes used in building wiring. The product complies with IEC/EN 61008, the standard governing residual current devices without integral overcurrent protection. Overall, the EFI6-P2 is a functional solution for leakage-current protection in single-phase electrical systems, combining 40 A rated current, 30 mA sensitivity, Type AC operation, 6 kA short-circuit rating, and standard DIN-rail mounting for distribution board applications.
