ETI EFI-P2 residual current device 2P 40A 0.3A type AC 10kA (2061232)

ETI EFI-P2 is a residual current device designed to protect people and electrical circuits from leakage currents and to improve safety in distribution systems. It is intended for use in residential, commercial, and small industrial installations where reliable disconnection in the event of a fault current is required. The device operates in AC circuits with a rated voltage of 230/240 V and a frequency of 50/60 Hz, which makes it suitable for common single-phase low-voltage networks. This model has a rated current of 40 A and a residual current sensitivity of 0.3 A. Such settings allow the device to monitor differential current in circuits where protection against leakage is needed without unnecessary tripping from minor disturbances. The AC type means the unit is designed to detect sinusoidal alternating residual currents. The 1+N pole configuration indicates one phase pole plus neutral, which is a standard solution for single-phase applications. The device has an instantaneous tripping function, so disconnection occurs without delay when a dangerous leakage current is detected. Its short-circuit withstand current Inc is 10 kA, which is an important parameter for installations where higher fault currents may occur. The device also complies with IEC/EN 61008, confirming its classification as residual current protective equipment. For installation, the EFI-P2 is mounted on a TH 35 DIN rail, making it compatible with standard modular distribution boards and enclosures. The housing depth is 68 mm, which should be taken into account when planning panel layout and wiring space. The IP20 degree of protection indicates that the product is intended for use inside protected electrical cabinets or switchboards, not in exposed environments. The connection range covers conductors from 1 mm² to 25 mm², providing flexibility for typical wiring solutions in household and commercial distribution circuits. With its 40 A rating, 0.3 A leakage sensitivity, 1+N configuration, and 10 kA short-circuit withstand rating, this residual current device is used as a protective element in systems where control of leakage current and safe circuit disconnection are required.
