Residual current device ETI EFI-P2 2P 63/0.03 A type AC 10kA (2061213)

ETI EFI-P2 is a residual current device intended to protect people and electrical circuits from leakage currents and to increase the safety of operation in single-phase networks. It is used in distribution boards of residential, administrative, and other facilities where fast disconnection without time delay is required when a fault current appears. The device belongs to the differential relay category and is designed for a rated current of 63 A with a residual current sensitivity of 0.03 A. Such parameters allow it to detect dangerous leakage currents in the protected circuit and disconnect the line at the appropriate threshold. The AC type means the RCD responds to sinusoidal alternating residual current, which makes it suitable for circuits with corresponding load characteristics. The pole configuration 1+N provides connection of the phase conductor and neutral conductor in one enclosure, which is a common solution for single-phase low-voltage networks. The rated AC voltage is 230/240 V, and the rated frequency is 50/60 Hz, so the device can be applied in networks with standard supply parameters. The short-circuit rated current Inc is 10 kA, which is important for operation in circuits where higher fault currents may occur. The device is installed on a TH 35 DIN rail, making it convenient to integrate into modular switchboards together with other protective and control equipment. The no-delay tripping time ensures immediate response in the event of leakage current detection. The housing has a depth of 68 mm, protection degree IP20, and supports conductor cross-sections from 1 to 25 mm². The product complies with IEC/EN 61008, confirming its designation as a residual current protective device. These characteristics make the ETI EFI-P2 suitable for group circuits, distribution nodes, and electrical panels where reliable differential protection and timely disconnection are required.
