2062533 Реле диференційне (ПЗВ) EFI-2 100/0,1 тип AC (10kA)

ETI EFI-2 is a residual current device intended for monitoring leakage currents and disconnecting an electrical circuit when a dangerous difference in current is detected. It is used in distribution boards of residential, commercial, and auxiliary electrical systems where additional electrical safety is required. The device belongs to the RCD category and is designed for single-phase circuits with a 1+N configuration. The unit is rated for a nominal current of 100 A and a residual current rating of 0.1 A, which defines its use in circuits with the corresponding protection requirements. Type AC means the device responds to alternating residual current. The rated AC voltage is 230 V, making it suitable for standard low-voltage networks. The rated short-circuit current Inc is 10 kA, which is an important parameter for systems where the protective device must maintain correct operation under high fault-current conditions. The product complies with IEC/EN 61008. Installation is carried out on a TH 35 DIN rail, which allows the device to be integrated into standard modular enclosures together with other rail-mounted equipment. The housing depth is 69 mm, so this should be taken into account during panel layout and wiring design. The device supports conductor cross-sections from 1 to 35 mm², providing flexibility for different connection schemes and cable sizes. The IP20 protection rating indicates protection against access to hazardous live parts with a finger or similar-sized object when the device is installed inside a closed enclosure. In practice, this residual current device is used as part of group or incoming protection, where leakage-current detection and automatic disconnection help improve the overall safety of the electrical installation. With its 1+N pole arrangement, 100 A rated current, 0.1 A sensitivity, and 10 kA short-circuit rating, ETI EFI-2 is suitable for use in distribution boards that require a standard modular format and compliance with established protective-device requirements.
