Descrizione
Three-phase four-wire mains EMI filter for suppressing electromagnetic interference in power lines of 3f systems. It is intended for installations with higher current loads, where it is required to limit the propagation of interference between the power network and the connected equipment (e.g. switchboards, industrial power supplies, converters and other power electronics).

Package contents
1× EMI filter CW4M-20A-R
Why choose this product?
Clearly defined electrical parameters for 3ph network 380 VAC and current 20 A
Industrial design with metal housing and terminal block for fixed installation
Suitable solution for reducing the propagation of high-frequency interference in power lines
Installation and operating instructions
Connect according to the terminal markings: input (LINE) and output (LOAD) for L1, L2, L3 and N; connect the protective conductor to terminal G.
To achieve effective filtration, install the filter as close as possible to the point where power enters the device and minimize the length of unshielded wires.
Ensure a firm mechanical attachment through the mounting holes and reliable grounding of the metal casing.
Safety notice
The device is designed to work with a dangerous mains voltage of 380 VAC. Installation may only be carried out by a qualified person.
Always disconnect the power supply and verify that there is no voltage before assembly, wiring or maintenance.
The protective earth (G/PE) must be connected correctly and with low impedance; incorrect earthing can reduce the filtration efficiency and increase the risk of injury.
