Residual Current Circuit Breaker EFI-P2 AC 25/0.5 002061241

Protection and safety in your electrical installation

Residual Current Circuit Breaker EFI-P2 AC 25/0.5 is a key element ensuring safety in every electrical circuit. Its function is to protect against electric shock, both in the case of direct and indirect contact with live elements. Additionally, it protects devices from potential fire hazard resulting from insulation damage. Installed in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated, it provides a reliable barrier against dangerous situations.

This two-pole residual current circuit breaker with a rated current of 25A and AC sensitivity of 0.5A is perfect for protecting circuits requiring high protection efficiency. Its AC technology-based design means sensitivity to alternating differential currents – this is important when protecting electrical devices from the effects of short circuits and overloads. Using a circuit breaker with such characteristics allows for a quick response in the event of a dangerous leakage current being detected, minimizing the risk of damage and threat to life.

Construction features and mounting

The EFI-P2 AC 25/0.5 circuit breaker is characterized by a solid construction and easy mounting on a DIN rail. Its width of 2 modules allows for efficient use of space in the distribution board. The cross-section of the connected multi-core and solid-core wire is 25 mm², which allows connection of wires of appropriate thickness, ensuring a stable connection and minimizing the risk of overheating. The IP20 degree of protection guarantees protection against accidental contact, and the conditional short-circuit strength at the level of 10 kA ensures its reliable operation even in difficult operating conditions.

Additional functions, such as a test button allowing you to check the correct operation and an indicator of the main contact position, make it easier to identify the status of the circuit breaker (ON/OFF), increasing comfort of use for both the installer and the end user. Protection of terminals against contact under voltage and the possibility of sealing the lever further increase the level of installation safety. The terminal design allows the use of insulated busbars on both the upper and lower terminals, which facilitates mounting and cable organization.
