Residual current circuit breaker EFI-P2 AC 40/0.03 002061212

Safety and protection in your electrical installation

The EFI-P2 AC 40/0.03 residual current circuit breaker (RCCB) is a key element ensuring the safety of using the electrical installation. It serves to protect against electric shock, both in the case of direct and indirect contact with live conductors. Additionally, it protects electrical devices from damage caused by short circuits or leakage currents. It is a reliable protection for homes, apartments, workshops and other facilities.

This two-pole residual current circuit breaker with a rated current of 40A and a sensitivity of 0.03A (30mA) is designed to operate in AC (alternating current) networks. Its AC technology-based design means it reacts to alternating current differential currents, providing effective protection under typical operating conditions. The rated differential current value of 0.03A ensures a quick response in the event of a dangerous leakage current, minimizing the risk of electric shock.

Installation and technical parameters

The EFI-P2 AC 40/0.03 circuit breaker is mounted on a DIN rail, which facilitates its installation and replacement. Its width of 2 modules allows for efficient use of space in the distribution box. The connection terminals allow the connection of wires with a cross-section from 1 to 25 mm², both solid and stranded. The degree of protection IP20 provides protection against accidental contact, but does not protect against the action of water - therefore, the circuit breaker should be mounted in a dry and well-ventilated place.

• Short-circuit strength: 10 kA – ensures resistance to the effects of short circuits in the installation.
• Rated voltage: 240 V – adapted to standard electrical networks.
• Frequency: 50/60 Hz – compatible with most power systems.
• Impulse withstand voltage: 0.4 kA - increases reliability in the event of sudden overvoltages
• Ambient temperature: -25 to 55°C – enables operation in a wide temperature range.

Application and compliance with standards

The EFI-P2 AC 40/0.03 residual current circuit breaker is used in lighting circuits, socket circuits and in protecting electrical devices with a power of up to 9kW (at 230V). It meets the requirements of IEC EN 61008, which guarantees its safety and reliability. It is a product of the renowned manufacturer ETI Polam, known for its high-quality electrical installation components. This circuit breaker is an ideal solution for both professional installers and end-users looking for effective protection for their electrical installation and life.
