Residual current circuit breaker EFI-P4 AC 25/0.03 002061611

Safety First

The Residual Current Circuit Breaker EFI-P4 AC 25/0.03 is a key element of any electrical installation, providing protection against electric shock. This device effectively reacts to leakage currents, minimizing the risk of danger to people and property. Its solid construction and compliance with safety standards guarantee reliable operation for a long time.

This circuit breaker is designed to operate in TN-S, TN-C-S, TT and IT networks, where the neutral and earth conductors are separated. With a residual current sensitivity of 0.03A, it provides a quick response in the event of insulation failure or direct contact with live conductors. This is particularly important in rooms with high humidity, such as bathrooms or kitchens, as well as in installations powering electrical devices exposed to insulation damage.

Parameters and Application

The EFI-P4 AC 25/0.03 circuit breaker is characterized by a rated current of 25A and a rated voltage of 415V (with an insulation voltage of 440V). It has 4 poles and is designed for mounting on a DIN rail – a standard solution that facilitates installation and replacement. Its width of 4 modules allows for efficient use of space in the distribution board. The short-circuit strength of 10kA ensures resistance to the effects of short circuits in the installation. The cross-section of the connected multi-wire and solid-core conductor is 25 mm², which allows you to connect conductors of the appropriate thickness, ensuring a safe and stable connection.

The application of the EFI-P4 AC 25/0.03 residual current circuit breaker includes the protection of lighting circuits, socket outlets and electrical devices exposed to electric shock. It is an essential element of protection in every home, apartment, office or workplace. Thanks to its reliability and effectiveness, this circuit breaker provides peace of mind for users and minimizes the risk of dangerous situations.
