2062532 Реле диференційне (ПЗВ) EFI-2 100/0,1 тип A (10kA)

ETI EFI-2 is a residual current device intended for protection of electrical circuits against leakage currents in residential and commercial distribution boards. It is used where it is necessary to monitor dangerous current paths to the enclosure or to earth and disconnect the line in time, helping reduce the risk of electric shock and insulation damage to equipment. The device is rated at 100 A with a residual current of 0.1 A, so it is suitable for circuits with the corresponding load level and sensitivity requirements. Type A means the device responds to sinusoidal alternating residual current and pulsating direct residual current. This makes it appropriate for circuits with electronic equipment, household appliances, and other loads where such leakage current forms may appear. The model is designed for 230 V AC and has a 1+N pole configuration, which matches single-phase networks with a neutral conductor. Installation is carried out on a TH 35 DIN rail, allowing easy integration into standard electrical panels together with other modular devices. The housing depth is 69 mm, which should be considered during panel layout and enclosure planning. The permitted conductor cross-section is 1–35 mm², providing compatibility with a wide range of cables and wiring connections. The short-circuit withstand current Inc is 10 kA, which is important for the device’s operation in electrical systems where higher fault currents may occur. The IP20 protection rating indicates basic protection against solid foreign objects and confirms that the device is intended for installation inside enclosed distribution boards. Compliance with IEC/EN 61008 confirms that it belongs to this class of residual current protective devices and meets the relevant technical requirements for such equipment.
