ETI EFI6-P2 Residual Current Device 2P 63A 0.03A Type A 6kA (2061263)

ETI EFI6-P2 is a residual current device designed to protect people from electric shock and to monitor leakage currents in low-voltage electrical installations. It is used in residential, commercial, and similar distribution systems where fast disconnection is required when a dangerous differential current appears. The device is mounted on a TH 35 DIN rail, which makes it suitable for installation in distribution boards together with other modular components. This model has a 1+N pole configuration, meaning one protected pole and neutral. The rated current is 63 A, while the residual operating current is 0.03 A, so the device is intended for circuits where a high level of protection against earth leakage is required. Type A means the RCD responds not only to alternating residual current, but also to pulsating direct residual current. This is important for circuits with electronic loads and household appliances that may create non-sinusoidal leakage currents. The nominal AC voltage is 240 V, and the rated frequency is 50/60 Hz, which allows the device to be used in standard single-phase networks. The short-circuit rated current Inc is 6 kA, providing the necessary margin for operation in typical residential and small commercial installations. The disconnection is instantaneous, without time delay, so the circuit is opened as soon as a hazardous leakage current is detected. The device complies with IEC 61008-1, the standard for residual current-operated circuit-breakers without integral overcurrent protection. The connection range covers conductors from 1 mm² to 25 mm², which supports use with common wiring sizes in distribution panels. The housing depth is 70 mm, and the IP20 degree of protection indicates indoor installation inside electrical enclosures, where accidental contact with live parts is limited. ETI EFI6-P2 63/0.03 Type A is a practical solution for residual current protection and leakage current monitoring in systems that require reliable circuit disconnection under fault conditions.
