Residual Current Circuit Breaker EFI-P2 A 40/0.5 002061142

Residual Current Device (RCD) is a key element of any electrical installation, providing protection against electric shock and preventing fires. The EFI-P2 A 40/0.5 model is a reliable solution designed for both professional installers and end-users. Its function is to quickly disconnect the circuit in the event of a leakage current to ground, minimizing the risk to life and property.

Functionality and application

This two-pole RCD with a rated current of 40A and sensitivity A is designed to operate in AC networks with a voltage of 240V and a frequency of 50/60Hz. Its construction based on type A technology means that it reacts to both alternating currents and pulsating direct currents – which is particularly important in modern installations powering electronic devices. The RCD is used to protect circuits with a conductor cross-section from 1 to 25 mm², both solid and stranded. Mounting is done on a standard DIN rail, which facilitates integration with existing electrical infrastructure.

Safety and technical parameters

The RCD is characterized by a high surge current resistance (0.4 kA) and short-circuit withstand capacity at 10 kA, which guarantees its reliable operation even in difficult operating conditions. The protection degree IP20 provides basic protection against accidental contact. It is worth noting the rated insulation voltage Ui of 440V, which confirms the high quality of workmanship and safety of use. Additionally, the presence of a "Test" button allows the end-user to regularly check the functionality of the RCD.

Ease of installation and additional features

The terminal block design allows the use of insulated busbars, which greatly simplifies and speeds up installation. The ability to seal the lever in the "On" and "Off" positions provides additional protection against unauthorized changes to the RCD status. Compact dimensions (2 module width) allow for efficient use of space in the distribution board. Therefore, the EFI-P2 A 40/0.5 RCD is not only a protective element but also a convenient and practical solution for every installer.
