Residual Current Device (RCD) EFI-4 A 80/0.03 002062545

Safety and protection in your electrical installation

Residual Current Device (RCD) is a key element of every electrical installation, providing protection against electric shock and safeguarding devices from damage caused by short circuits and overloads. The EFI-4 A 80/0.03 model is a four-pole switch designed to operate in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated. Its function is to quickly disconnect the circuit in the event of a current difference, minimizing the risk of electric shock and preventing fires resulting from insulation damage.

Construction and parameters – robustness and reliability

The switch is characterized by a solid construction for mounting on a DIN rail, ensuring stability and ease of installation. Its rated current is 80 A, and the rated residual current is 30 A – these values guarantee effective protection in typical domestic and industrial installations. The short-circuit strength of 10 kA demonstrates its resistance to sudden current surges. Compact dimensions (width 4 modules, depth 68 mm) allow for easy adaptation to an existing distribution board. The use of type A means sensitivity to alternating and pulsating DC differential currents, providing comprehensive protection.

Functionality for professionals and users

This switch not only meets the highest safety standards but also offers a range of practical solutions to facilitate installation and operation. The ability to connect wires with a cross-section from 1 to 25 mm² ensures compatibility with various types of cabling. The contact position indicator makes it easy to identify the switch status (ON/OFF), and the test button allows regular checking of its correct operation. Additionally, the ability to seal the lever protects against accidental switching on or off of the device. A wide operating temperature range (-25 to 55 °C) guarantees reliability in various environmental conditions. Thanks to this, both installers and end-users can be sure of the reliable protection of the electrical installation.
