Residual current circuit breaker EFI-P4 A 25/0.1 002061521

Safety and protection in your electrical installation

The EFI-P4 A 25/0.1 residual current circuit breaker (RCCB) is a key element ensuring safety in every electrical circuit. Its function is to quickly disconnect the power supply in the event of a ground fault current being detected, minimizing the risk of electric shock and preventing fires. This is a reliable protection for both the installation and the people using it.

Functionality and application

This four-pole (4P) circuit breaker with a rated current of 25A and A sensitivity is designed to protect against differential currents of 0.1A. This means it reacts to both alternating current (AC) and pulsating currents, making it a universal solution for a wide range of applications. It is suitable for protecting circuits with a conductor cross-section from 1 to 25 mm², both solid and stranded. Mounting is done on a standard DIN rail, which simplifies integration with existing electrical infrastructure.

Key features and benefits

• High reliability: ETI POLAM circuit breakers are characterized by a solid construction and undergo rigorous quality tests, guaranteeing long-lasting and trouble-free operation.
• Fast response: A sensitivity ensures quick detection of even small leakage currents, minimizing the risk of electric shock.
• Versatility: Suitable for use in TN-S, TN-C-S, TT and IT networks.
• Durability: Withstands short-circuit currents up to 10kA, protecting the installation from serious damage.
• Easy installation: Standard DIN rail mounting simplifies installation and replacement of the circuit breaker.
• Safety: IP20 protection degree provides protection against accidental contact with energized parts.
• Contact position indicator: Allows quick identification of the circuit breaker status (ON/OFF).
• Tamper-proof: Can be sealed to prevent unauthorized disconnection of the circuit breaker.

Technical parameters in practice

A rated current of 25A means that the circuit breaker is designed to operate with circuits with an average load – ideal for protecting sockets, lighting or small electrical appliances. The 0.1A sensitivity provides effective protection against dangerous leakage currents that may occur, for example, in damaged devices or installations. The short-circuit strength at 10kA guarantees that the circuit breaker will not be damaged during a short circuit in the network, and its operation will be quick and effective. The rated voltage of 415V allows it to be used in most standard electrical installations found in residential and commercial buildings. The cross-section of the connected stranded wire is from 1 to 25 mm², and the degree of protection is IP20.

Compliance with standards

The EFI-P4 A 25/0.1 residual current circuit breaker meets the requirements of IEC EN 61008 standard, which confirms its safety and high quality of workmanship. This guarantees compliance with applicable regulations and industry standards.
