Residual current device ETI EFI-P2 2P 63/0.1A type AC 10kA (2061223)

ETI EFI-P2 is a residual current device intended for monitoring leakage currents and disconnecting the circuit when a dangerous difference in current is detected. It is used in residential and commercial electrical networks where additional protection of people and equipment is required. The device is suitable for installation in distribution boards and other shielded assemblies with standard modular mounting. This model has a 1+N pole configuration, meaning one protected pole and a neutral conductor. The rated current is 63 A, and the residual operating current is 0.1 A, which defines the trip threshold for differential current. Type AC means the device responds to sinusoidal alternating residual currents. Tripping is instantaneous, without delay, which is important for fast disconnection in fault conditions. The rated AC voltage is 230/240 V, and the operating frequency is 50/60 Hz, so the device is compatible with common single-phase supply networks. The nominal short-circuit current Inc is 10 kA, indicating suitability for systems with the specified fault current level. The device is mounted on a TH 35 DIN rail, which simplifies installation in standard electrical enclosures together with other modular apparatus. The body depth is 68 mm, which should be considered when planning the layout inside the panel. The permissible conductor cross-section is 1 to 25 mm², allowing connection of a wide range of conductors used in distribution circuits. The IP20 protection degree provides basic protection against contact with live parts and is intended for use inside enclosed switchgear. The device complies with IEC/EN 61008, the standard governing residual current devices. As a differential protection element, this ETI unit is used to increase the safety of electrical installations by detecting leakage currents and disconnecting the affected circuit. Its electrical ratings, 1+N pole design, and DIN-rail mounting make it a practical solution for single-phase distribution lines in panels where standardized modular installation and fast fault response are required.
