Residual current circuit breaker EFI-P4 AC 16/0.03 002061610

Safety first – EFI-P4 AC 16/0.03 residual current device (RCD)

This four-pole residual current device (RCD) is a key element of any electrical installation, providing protection for people and devices against the effects of electric shock and damage caused by short circuits and overloads. The EFI-P4 AC 16/0.03 model, manufactured by ETI POLAM, combines reliable operation with compact dimensions, making it easy to install even in crowded distribution boards.

Protection tailored to your needs

This RCD is characterized by a rated current of 16A and a residual current sensitivity of 0.03A. This means it reacts to small leakage currents, which may indicate damage to insulation or direct contact with live conductive elements. This ensures a high level of safety when using the electrical installation. Designed for use in AC (alternating current) networks, it is ideal for protecting lighting circuits, sockets in residential and office premises, and electrical devices sensitive to interference.

Installation and technical parameters

The RCD is mounted on a standard DIN rail, which greatly simplifies the installation and replacement process. Its width of 4 modules allows for efficient use of space in the distribution board. The RCD is adapted to connect multi-core and solid-core wires with a cross-section of 25 mm², providing flexibility in choosing the appropriate cables. The short-circuit strength of 10 kA guarantees its proper operation even in the event of serious failures in the network. The IP20 degree of protection protects against accidental contact. The rated voltage of 415V and the insulation voltage Ui of 440V ensure safe operation in standard electrical installations. The impulse withstand voltage is 0.4kA.

For installers – quick installation and reliable operation

* Easy mounting on DIN rail – saves time during installation.

• Clear markings – facilitate identification and configuration of the RCD.

• High quality workmanship – guarantees reliability and long service life of the device.

• Terminals adapted to different types of wires – flexibility in choosing materials.

• Conditional short-circuit current 10kA - provides protection in the event of short circuits in the network with appropriate fuse protection.

For users – safety and peace of mind

* Effective protection against electric shock – increased safety for you and your family.

• Protection of electrical devices – protection against damage caused by overvoltage and short circuits.

• Contact position indicator – easy control of the RCD status (ON/OFF/TRIP).

• Test button – possibility of regular checking of the correct operation of the RCD (periodic tests recommended!).

• Compliance with safety standards - ensures operation in accordance with applicable regulations.
